2026 Forest River Stealth 4017GX Review
Featuring the 2026 Forest River Stealth 4017GX
Most people who stop at the 2026 Forest River Stealth 4017GX want the same two things: a garage that earns its keep and a house that doesn't feel like an afterthought. This one runs 45 feet, three slides, sleeps 8, and the layout is center kitchen, center living, front bath and front bedroom, with rear entertainment at the back end. GVWR is 21,000 lbs against a 15,674 lb dry weight, so there's 5,326 lbs of cargo capacity to work with. Two entry doors keep garage traffic out of the kitchen.
Utah gives you four very different seasons inside about six hours of driving, so here's how the equipment on this unit actually gets used.
Spring desert trips in the 2026 Forest River Stealth 4017GX
Spring is dry camping season. Moab, the San Rafael Swell, Little Sahara. There are no hookups out there, and that's where the 600W solar system (the upgrade adds two more 200W panels to the 200W standard) plus the 6.0 NPS generator do the heavy lifting. Run the generator when you're charging hard or running the air, let the panels carry the quiet days.
Water is the other limit. This one carries 150 gallons fresh, 120 grey and 80 black, which is a long leash for a group of eight if you're smart with showers. The black tank flush means you're not fighting a dirty tank after a week in the dust, and the lockable Nautilus utility station keeps your connections in one place.
Desert gear is bulky and filthy. Dirt bikes, fuel cans, chairs, awning mats. The 3,000 lb ramp door loads heavy machines without a sketchy approach, and the garage package is on this unit. Pass-through storage takes the things you don't want inside after a day in the sand.
Tow math matters more in spring than people admit, because you're often climbing out of a canyon loaded to the gills. Hitch weight is 3,765 lbs and exterior height is 13.5 feet, so check your truck and check your storage building before you buy.
Summer in the mountains
Mirror Lake Highway, the Uintas, Fish Lake, Strawberry. Summer camping in Utah is a shade game, and the 10.83 ft awning is what you'll live under from about two in the afternoon on.
The 3 season rear patio door on this unit turns the garage into a covered deck once the ramp is down, which is where most people end up eating when the bugs aren't bad. Flip Tread solid entry steps hold up better than folding steps on soft, uneven forest sites, and the undercarriage LED lighting helps when you're setting up after dark because you underestimated the drive.
Inside, the 10.7 cu. ft. 12V refrigerator is the piece that makes mountain weekends work without shore power, since it runs off the battery bank the solar is feeding. Add the 3 burner residential style cooktop and the kitchen island and you can actually cook for a crew instead of reheating.
Forest roads chew up trailers. The CRE-3000 Mor-Ryde suspension system with wet bolts is there for the washboard between the pavement and the lake, and it's one of the specs worth knowing if you're comparing this Forest River toy hauler against lighter-built competition.
Fall hunting and colour runs
Fall is when the 60k BTU tankless water heater pays for itself. Four hunters back from a cold morning, four hot showers, no waiting for a tank to catch up. The walk thru bath means someone can get cleaned up without blocking the hallway for everyone else.
Nights get long in October. The entertainment slide out with fireplace gives you somewhere warm to sit when it's dark at six, and the 35k BTU ducted furnace with built-in vents handles the morning chill at elevation.
Sleeping eight in hunting camp usually means mixed groups and odd hours. There's a king bed in the front bedroom and the HapiJac electric rear bed drops down in the garage, so the garage crew and the bedroom crew can keep different schedules.
Hauling matters most this time of year. Game, coolers, firewood, a side-by-side and extra fuel add up fast, and that 5,326 lb cargo capacity is the number to weigh your plans against. The weatherproof insulated ramp door seals the garage back up once the toys are in.
Winter: what the build gives you
Be straight about this one. The facts on this trailer list an Alumifoil insulated enclosed underbelly, fiberglass roof and flooring insulation, vacuum-bonded aluminum framed sidewalls, a weatherproof insulated ramp door and a 35k BTU ducted furnace. That's real insulation and real heat for a cold snap or a late-season hunt.
What's listed on this unit's own sheet, though, is a 3 season rear patio door, so treat the patio setup as spring through fall and plan a true deep-freeze trip accordingly. Shoppers looking at a toy hauler for sale in Utah should ask us directly about winter use and how they intend to camp, rather than assuming any trailer is a January unit.
A few build details worth knowing
The one-piece roof membrane carries a 12 year warranty, which is the kind of spec that shows up years after you forget the sales conversation. The 98" peak pitched roofline gives the garage real vertical room for tall toys. The unit also carries the RVIA seal.
