2026 Forest River Alta 2870KTH-W Walkthrough
Hitching up on the 2026 Forest River Alta 2870KTH-W
Start where every trip starts, at the coupler. The power tongue jack does the lifting, and it has an LED light built into it, which matters more than you'd think the first time you're hitching in a dirt lot after sunset. Hitch weight is 1,350 pounds, dry weight is 8,633, and the GVWR is 11,700 on two axles. Cargo capacity is 4,717 pounds, which is a genuinely big number and the reason this floorplan works for people who haul heavy.
The frame underneath is an automotive powder coated drop frame, and the drop is what gives you the garage floor height and the storage volume in the pass-through. Walk the length and you're at 33 feet 1 inch, 8.42 feet wide, 12.42 feet tall. Measure your garage door and your parking pad before you fall in love with it.
Load the pass-through before you load anything else. It's the easy win on departure morning: chairs, leveling blocks, the hose bag, the stuff you want without opening the main door.
Pulling in and setting up
Four-point electric stabilizer jacks mean setup is a button, not a crank handle and a flashlight. Get the trailer where you want it, drop the jacks, and the coach stops moving when someone walks across the floor.
The power awning runs 19 feet with LED lights in it, so one switch gets you shade over the whole door side and usable light under it after dark. There's one awning, and at 19 feet it covers a lot of patio.
Hookups are the next five minutes. Fresh water is 110 gallons, grey is 60, black is 30. That fresh tank is the headline for anyone who camps where there's no spigot, and a 200-watt solar package is available as an option to back it up alongside an 1,800 watt inverter, so you've got charging and real AC power without listening to an engine run. A 6K generator is available if you want to go further than the panels will take you.
Inside the door, the control panel is where you'll check tank levels and run the jacks and the awning. Learn that panel on the lot and you'll never stand outside guessing.
The garage is 14 feet. That's a dirt bike and a quad, or two bikes with room to work around them, or a side-by-side depending on what you ride. A separate 14-foot garage is the whole argument for a toy hauler over a conventional trailer, and this one is sized to actually use.
Cooking and eating
The kitchen gets designer solid surface countertops with a stainless steel sink, which is the surface you want when you're cutting, setting down hot pans, and wiping up after six people. The appliance package is the upgraded residential inspired one: a 3-burner range with an oven, and a 10.7 cubic foot 12-volt residential inspired refrigerator. That fridge size is the difference between shopping once for the weekend and shopping twice.
Hot water comes from a tankless water heater with a bypass. Nobody waits for a tank to recover, so dishes and showers don't have to be negotiated, and the bypass makes winterizing straightforward.
There's an outdoor kitchen on this unit too, which changes how you cook in warm weather. You keep the heat, the smoke and the traffic outside under the awning instead of running it all through the living space.
The evening
Two slides open the living space up, and they're flush floor slide outs, so there's no lip to catch a toe or a chair leg where the floor steps out. Both slides and the rear wall are built from the same 2-inch fully laminated construction as the side walls.
Entertainment is a 2-zone sound bar with Bluetooth and HDMI connectivity, so you can run audio in two areas and plug a console or a streaming stick straight in. There's an amplified TV antenna with WiFi prep for over-the-air channels and for adding a signal booster later.
When the temperature drops (and in Utah it drops hard once the sun is off the canyon walls), the heated floors do the work. They're insulated forced air heated floors, fed off the furnace, so the floor itself is warm instead of just the air above it. Add the enclosed and heated underbelly and the 5-inch vacuum bonded roof, and the whole shell is built to hold temperature. An extended climate guard package is available if you plan to push the shoulder seasons.
Sleeping
Sleeps 6. There's a king bed, which is rare in this class and worth sitting on, plus bunks for the kids or for gear that shouldn't ride in the garage.
The bathroom is a full one, and with the tankless water heater behind it, a shower at 10 p.m. doesn't depend on who showered at 9.
Packing up in the morning
Morning teardown runs in reverse and it's fast. Awning in, jacks up, slides in, tongue jack down onto the ball. Load the bikes into the 14-foot garage, strap them down, and the heavy stuff you'd otherwise wrestle into a pickup bed is already riding at axle height.
The 5/8-inch tongue and groove plywood floors and the fiberglass front cap are the parts you notice over years rather than weekends: a floor that doesn't flex under a loaded bike and a front cap that sheds highway debris. Goodyear tires, a ladder, and a spare tire and carrier are all available.
If you've been shopping for a new toy hauler and getting frustrated by garages that measure shorter than advertised, this is the floorplan to walk through. We stock Forest River toy hauler inventory here in Millcreek, and a 14-foot garage with 4,717 pounds of cargo capacity narrows the field fast for anyone searching for a toy hauler for sale in Utah.
Come see how it sets up. Drop the jacks, run the awning out, walk the garage with a tape measure, and sit on that king bed. You can also check current photos and details on the live listing.
Frequently asked questions
What is a toy hauler, and how is this one different from a regular trailer?
A toy hauler has a dedicated cargo garage with a ramp-style opening, separate from the living space. This one gives you 14 feet of garage plus 4,717 pounds of cargo capacity, so your bikes or UTV ride inside the trailer instead of in a truck bed.
What do I need to tow it?
Hitch weight is 1,350 pounds, dry weight is 8,633, and GVWR is 11,700 pounds on a tandem axle. Load it anywhere near that GVWR and you want a three-quarter-ton truck with the payload to carry the tongue weight.
Can I camp off-grid in it?
Yes. You've got 110 gallons of fresh water and an 1,800 watt inverter, with grey at 60 gallons and black at 30, and a 200-watt solar package is available as an option. A 6K generator is available if you need more than the panels produce.
How many people does it sleep?
Six, with a king bed and bunks.
How long is it overall?
33 feet 1 inch, 8.42 feet wide and 12.42 feet tall, so check your gate and garage clearance before you bring it home.
