If you’re hunting for a fifth wheel that brings serious comfort, residential features, and enough room to truly relax, the Solitude 310GK 5TH WHEEL is worth a closer look. Built by Grand Design, this model gets a lot of love from full-time RVers and vacationers alike. I’m going to walk you through the details, features, and real-world experience so you can decide if this is the fifth wheel for your road adventures.

If you’re new to the Grand Design Solitude series, you’ll notice right away that these RVs are built to feel more like a home than a camper. They carry a reputation for solid build quality, smart storage, and layouts that make daily life on the road feel just a little more normal. So let’s run through everything you’ll want to know about the 310GK.
Who Should Consider the Solitude 310GK?
I’ve recommended the Solitude 310GK to a range of RVers over the years, but it really shines for folks looking for a mix of comfort, towability, and full-time friendly features. If you need a huge amount of space for a big family, you might want to look at Grand Design’s longer floorplans. But for couples, singles, or anyone who regularly hosts a guest or two, the 310GK’s layout just works. It’s also great for those who want to stay out during colder months thanks to its insulation package.
The fifth wheel format provides serious towing stability, and the length (just under 35 feet) strikes a balance between premium amenities and campground accessibility. I’ve talked with full-timers who love that it’s easy enough to tow with one-ton pickups (properly equipped, of course) but roomy enough inside that you forget you’re in an RV.
About Grand Design and the Solitude Series
Grand Design RV, based in Indiana, has pumped out quality towable RVs since 2012, but the folks behind it have RV roots going back decades. What’s made them a go-to brand is their attention to feedback from real owners. The Solitude line is their flagship luxury fifth wheel series and represents their top-of-the-line craft in both features and build.
What gets a lot of owners talking is Grand Design’s focus on service and support. When researching models, I always check for owner forums and review groups, and Grand Design consistently gets high marks in communication, fixing warranty issues, and overall customer happiness.
The Solitude 310GK, in particular, hits a sweet spot for those seeking a premium fifth wheel that doesn’t tip into being unmanageably long or heavy. If you’re looking to get off the beaten path, Grand Design is known for good underbelly heating and insulation, making the Solitude series comfortable for all-season use. Many folks even use these as their main home. That’s no joke.
The Solitude 310GK Floor Plan Walkthrough
Let’s break down what you’ll find inside, front to back. The 310GK floor plan feels open without losing practical storage. Walking in, you’re greeted by a huge living/kitchen area, and the rear lounge is set up to maximize both seating and views.
Main Living Area
The main slideouts make this area feel extra spacious. Most units come with comfy theater seating across from a retractable 50” TV and electric fireplace, plus a trifold couch in the rear that doubles as a guest bed. During my time in a 310GK, I could easily see myself lounging here during a rainy day, or hosting friends for movies in the evening. Big panoramic windows wrap the space in natural light, which is something you’ll appreciate after a few days at camp.
Kitchen Setup
The kitchen in the 310GK is a strong point. You get a large kitchen island with stainless sink, roomy pantry, solidsurface countertops, and a real residential oven (not those tiny RV ones). There’s a fullsize fourdoor fridge in many upgrades or a double door in others, and tons of cabinet space. I’ve cooked a few meals in this setup and found it comfortable to work in; plus, the overhead venting is actually up to the task. Undercabinet lighting and pullout trash keep it feeling modern and clean.
Dining Nook
The freestanding table and chairs aren’t bolted to the floor like in some cheaper RVs, so you’ve got a real spot to work, eat, or play cards. Windows all around the dinette, too, so you don’t feel boxed in.
Bedroom and Bathroom
Moving forward, you’ve got a hallway that leads to a split bath. The bathroom is big enough to actually use like a normal home bathroom, with a onepiece fiberglass shower (yay, no leaking seams), porcelain toilet, medicine cabinet, shelving, and lots of hot water thanks to the large capacity water heater.
The main bedroom easily fits a king (with a queen option for more walkaround space), massive wardrobe at the front, individual reading lights, washer/dryer prep, and lots of overhead storage. RV beds can often feel like an afterthought, but Grand Design goes all in with real mattresses and durable frame construction here.
Interior Storage
I’m always hunting for good storage in an RV, and the 310GK is loaded. Besides the big front closet, you get dressers, underbed storage, kitchen drawers, and pantry space. Even with two people living in it fulltime, storage rarely feels tight.
Exterior Features, Basement, and Construction
The outside of the Solitude 310GK says “residential” as much as the inside. Two awnings cover nearly the entire patio side, meaning you can create a shady hangout on hot days. There are outdoor speakers, LED lighting, and easy access steps. Grand Design uses a sturdy dropframe construction, allowing for a huge passthrough storage area underneath. I managed to stuff camp chairs, fishing gear, a grill, a table, and several tubs in there with room to spare; no exaggeration.
The walls are vacuumbonded for strength, and the insulation package includes doublelayered floors and ceiling for temperature control and noise reduction. That’s especially helpful for folks parking near busy highways or in yearround weather.
There’s also an outdoor spray port for quick cleanup, dedicated spots for garbage cans, a universal docking station for connections, and a covered power cord reel. Everything is set up to make packing up and setting up super quick. That matters when the weather isn’t cooperating.
Insulation, Heating, and Full-Timing Capability
This is where the Solitude 310GK stands out compared to lots of competition. Grand Design takes allweather camping seriously. There’s a full enclosed underbelly with forced air heat, heated storage, and extra insulation in the roof and slide floors. For RVers wanting to chase winter or stay cool in the hottest summer regions, this really helps keep comfort and plumbing running smoothly.
The standard furnace throws out plenty of heat and, as long as the propane is topped off, handles freezing nights well. The residential air conditioning (sometimes upgraded to two or more units) chills the space quickly during the hottest part of the year. Add in the insulated windows and you’re in business for yearround use.
Towing and On-Road Experience
Towing a Solitude 310GK does take a properly equipped one-ton truck, but the length and balance make it pretty smooth on the road. The pin weight is around 2,350 lbs (empty), so you really need to watch weight limits and payload. I’ve trailered this down winding mountain passes and across windy plains, and it tracks right behind your truck without the drifting or swaying you sometimes see in lighter models.
Grand Design includes a MORryde CRE3000 suspension, which helps smooth out bumps and reduce shaking inside the rig. Optional disc brakes are available and are absolutely worth getting if you’ll be in the mountains or drive long distances; the stopping power is noticeably better. Automatic leveling is a pretty standard feature and saves tons of setup time.
Be aware that, with almost 35 feet in length, not every campground accommodates the 310GK easily. Always double-check site lengths before booking. Loop pullthrough sites and open countryside are where this RV feels most at home.
Entertainment, Wi-Fi, and Smart Features
The Solitude series really leans into the idea that modern RVers want reliable tech, and Grand Design delivers. The standard 310GK comes wired for Wi-Fi, satellite, and cable, and many come prepped for solar; pretty handy for boondocking, or if you want to cut down on generator noise. The living room’s entertainment center features a JBL soundbar, big screen HDTV, and Bluetooth connectivity. USB charging ports near the seating and in the bedroom keep devices ready to go.
Some owners swap out the stock sound system for even beefier options, but in my comparisons, the factory setup usually holds its own, especially compared to other RV brands at this price point.
Practical Everyday Living and Comfort
If you’re someone who wants an RV that actually feels like a home, the 310GK does a solid job here. The main living area is open enough for socializing or watching TV, and the kitchen is genuinely a pleasant place to make food. The heating and cooling keep up even in less-than-ideal weather, and the extra insulation means you’re not constantly fighting outside temperatures.
Sit down at the table in the morning with coffee, and you’re surrounded by big windows and interior lighting that’s soft, not harsh like some LED setups. The master bedroom is big enough to walk around without gymnastic moves, and the main closet has all the space you need for multiseason living. If you want to install a washer and dryer, it’s all prepped and ready; no fighting with weird plumbing kits or making holes yourself.
What I Like About the Solitude 310GK
- Well-thought-out floor plan that feels open but still cozy
- Residential appliances, including a real oven and large fridge
- Excellent storage, both inside and in the basement area
- Solid insulation for full-time or all-season use
- Quality fit and finish. Real wood doors, softclose drawers, sturdy hardware
- Easy automatic leveling and smooth towing
Potential Downsides and What to Watch For
- Heavier than many midsize fifth wheels. Requires a capable tow vehicle
- Length may limit pull-in options at older or smaller campgrounds
- Some features are tied to upgrades or special packages (double AC, bigger fridge, etc.)
- Stock mattress is good by RV standards, but many will still want to upgrade for full-time use
- Price can creep up fast with luxury options; keep an eye on add-ons
Grand Design’s quality control has improved, but as with any RV, it’s a good idea to do a full walkthrough before delivery, checking for cabinet fit, seals, and possible minor repairs needed straight from the factory or dealer. Most small issues are handled under warranty with minimal fuss, but it’s always better to catch things early.
Owner Support and the Grand Design Community
One thing I really appreciate is the online community and the responsiveness of Grand Design’s support team. There are active owners groups on forums and social media filled with folks who share advice, modifications, secret storage hacks, and more. Grand Design monitors this feedback and frequently addresses issues with design changes or recalls, so you know they’re listening to real users.
The warranty is straightforward: there’s a one-year bumper-to-bumper limited warranty, plus a three-year structural warranty. Grand Design’s customer service is known for moving quickly and being upfront about fixes, which is a relief compared to stories I’ve heard from other brands. Everything from slide functions to insulation performance is discussed openly online, so if you have a question, there’s almost always another owner ready to help.
Smart Upgrades and Customizations
One thing you’ll notice on owner forums is that folks love customizing their Solitude 310GK. Below are a few mods I’ve seen be particularly popular or worthwhile:
- Swapping out the factory mattress for a memory foam or custom short king (makes a huge comfort difference)
- Adding solar and a larger inverter for extended boondocking
- Installing a cell booster for stronger connectivity in remote locations
- Upgrading to disc brakes for longer trips or mountain driving
- Switching the factory recliners for custom, higher-back versions (great for taller folks)
- Extra shelving in the pantry and closets for maximizing storage
Since Grand Design builds these fifth wheels with flexibility in mind, there’s usually room behind panels and cabinets if you want to run cables, expand the entertainment system, or add lighting. The main electrical panel is easy to access, and the basement storage has plenty of room for a second battery or fresh water system if you plan to camp off-grid long term.
How the Solitude 310GK Stacks Up in Its Class
The fifth wheel market is packed with choices, and the 310GK takes on competitors like Keystone Montana, Jayco Pinnacle, and Forest River Cedar Creek. I’ve toured all of these, and the Solitude 310GK stands out in a few practical ways:
- Feels truly residential, not just “upgraded RV”
- Great balance between space and towability (not a monster trailer, but roomy)
- High-quality cabinetry and finishes; doors aren’t hollow core, latches are solid
- Real climate insulation for full-time use
- Storage is actually useful; you don’t have to get creative or add a ton of bins
Keystone and Jayco both make excellent luxury fifth wheels, but I find Grand Design’s design details, like garden windows, fullwidth storage, and the way the slides seal and operate, give them a small but real advantage. When looking at used models or dealer lots, check fit and finish. Grand Design’s reputation for less squeaking and rattling in the road has held true in the units I’ve taken out for extended trips.
Pricing, Packages, and Dealer Advice
Like most luxury fifth wheels, the Solitude 310GK price varies by dealer, region, and upgrades. Sticker pricing for a new unit is usually around $110,000, but it’s not unusual to see prices range from $90,000 for a lightly used model to as high as $130,000 for a fully loaded 2024 version with all the bells and whistles. Shopping around, being patient, and catching show specials or yearend clearance events can save you $10,000 or more.
Packages to know about:
- Residential Living Package: Includes big ticket items like the oven, large fridge, fireplace, and solidsurface counters
- Peace of Mind Package: Extra insulation, bestinclass storage solutions, and better furniture
- WeatherTek Package: Adds heavy upgrades to the insulation, heating, and underbelly
Most dealers will bundle these, or offer them as standard on preorder units, so you rarely need to choose them one at a time. If you care about particular features (double AC, residential fridge, solar prewire), always doublecheck the specific unit; sometimes they’re options rather than standard kit.
When you’re negotiating, don’t be afraid to ask for throwins. Extra slide toppers, upgraded staircases, or even prepaid maintenance can often be added on if you’re flexible about delivery timing or payment.
Maintenance and Durability
A fifth wheel like the Solitude 310GK needs regular care, but Grand Design makes it easier than most. The owners manual is actually useful (not always true in the RV world), with clear diagrams and troubleshooting steps. Routine checks, slide seals, rubber roof, tire health, propane lines, and water connections, are all accessible.
Owners who stick to annual inspections, especially before winter, tend to experience fewer problems. The walls and slides are better sealed than on a lot of competing brands, which keeps leaks and water damage at bay. One bonus that can’t be overhyped: customer support is reachable and will usually coordinate repairs if you’re on the road and out of your home region.
Real Owner Stories and Travel Experience
I’ve spent enough time in the Solitude 310GK to firmly say it suits both the occasional traveler and the full-time RVer. Several full-timers I know have crossed the US multiple times and reported very few issues beyond normal maintenance; cabinet latches here and there, an AC sensor or slide motor, all handled promptly under warranty.
Many owners travel for festivals, stay in National Parks, or even use theirs as a base for business on the road. If you’re on the fence because of the size, it’s worth seeing one in person. Many say the floorplan looks “big” on paper, but once you walk inside, it just feels “right.” The blend of openness and cozy corners is what keeps folks satisfied year after year.
Tips for Buying and Maximizing Your 310GK
- Rent a Solitude 310GK for a weekend or longer if possible to get a true sense of space and livability
- Check all appliances, slides, and water systems during the pre-delivery inspection
- Join the Grand Design owners groups; there are meetups, mods, group travel, and tons of practical tips
- Consider upgrading tires and brakes if you’ll be traveling across the Rockies or similar mountain ranges
- Don’t skimp on surge protection or extra hoses for all four seasons. You’ll thank yourself later
For anyone who’s new to RV life, the Solitude 310GK will surprise you at how much it can feel like home. Having spent time on the road with this model, I appreciate the balance of size, comfort, and ease of use. Set-up and tear-down are manageable solo, and all the major systems are userfriendly even for RV newcomers.
Frequently Asked Questions (FAQ) About the Solitude 310GK
- Is the Solitude 310GK suitable for full-time living? Absolutely. Many owners live in theirs year-round and find it holds up well. The insulation, storage, and livability factor are big reasons for choosing it over other models.
- Can the 310GK be towed with a three-quarter ton truck? Not recommended. It’s really better suited for one-ton trucks. Look for models with at least a 3,500 lb. payload.
- What are some good add-ons to consider? Solar panels, a second air conditioner, upgraded mattress, and disc brakes are popular upgrades. Slide toppers help keep debris out, and rear view camera kits are super useful for backing in.
- How many people can it sleep? The main bed and trifold sofa can handle 4 adults, but it’s designed mainly as a luxury couples’ unit.
- Does it handle winter weather? Yes. If you keep propane topped up, the furnace and insulation package keep things cozy down to at least freezing and often below with proper prep.
Final Thoughts: Is the Solitude 310GK the Right Fifth Wheel For You?
If you’re after a fifth wheel that feels like a real home, travels well, and stays comfortable all year, the Solitude 310GK should be on your shortlist. The attention to quality and owner feedback has led to a fifth wheel that feels balanced in all the ways that matter: space, comfort, storage, and durability. Whether you’re full-timing, snowbirding, or just exploring the country on weekends, the 310GK brings a lot of value for the money. Features like an actual kitchen island, big storage areas, and year-round comfort make it a smarter long-term choice than most.
I’d recommend walking through one in person if possible. Pictures don’t quite do justice to the open layout and finishes. And as always, careful research helps buyers make informed decisions. There’s a reason you see so many Solitudes racking up the miles across North America. They just work for real people, and Grand Design’s reputation for support means you aren’t left alone if something goes wrong on the road.
