2026 Forest River Campsite Ultra25JT

The Campsite Ultra 25JT leaves Forest River's factory at 6,808 lbs dry, with a published GVWR of 7,735 lbs and 927 lbs of cargo capacity between the two. Cargo capacity is 12% of the loaded rating, and Forest River's own definition is worth reading before you plan against it: cargo capacity is what remains for fresh water, gear, food, batteries and every dealer-installed accessory. Fresh water alone is 8.3 lb per gallon, so filling this trailer's 52-gallon fresh tank spends 432 lbs of that 927 lbs before anything else is loaded.

Dry tongue weight is 735 lbs, or 11% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits inside it as published. Tongue weight is not fixed: it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A weight-distribution hitch is the normal fitment at this tongue load, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit.

Tank capacities are 52 gallons fresh, 38 grey and 28 black, 66 gallons of waste capacity against 52 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Forest River publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.

Against the rest of the Campsite Ultra roster this is the 5th of 6 floorplans by dry weight, in a line that runs from 5,158 lbs to 6,923 lbs. It sits in the heavier third of the line. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.

A useful way to read the pair of weights is to stop planning against the dry figure. Nobody tows a trailer at 6,808 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity, which is modest for a family trip, and this plan is already near 7,272 lbs on the road. Compare that number against the tow vehicle, not the dry weight, and leave margin on top of it - the published GVWR of 7,735 lbs is a limit rather than a target.

Every number above was captured twice from Forest River and checked against itself before it was published. The line roster block and the individual floorplan page are two separate factory renderings of the same trailer, and this plan's 4 shared figures agree exactly on both. Dry weight plus cargo capacity also equals the published GVWR exactly, which is the arithmetic check this site runs on every profiled floorplan. Where a figure is missing from this page it is because Forest River does not publish it in this channel, not because it was hard to find - and the row says so rather than being quietly dropped.

Forest River publishes no floorplan description for this plan in the channel this page is built from - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 25JT is a Campsite Ultra designation and this site does not decode it into a layout claim.

Campsite Ultra is the tightest roster on this site by loaded rating: GVWR spans just 7,600 to 7,985 lb across all six floorplans, a 385 lb spread. What actually varies is what the trailer spends that rating on. Dry weight runs 5,158 to 6,923 lb and cargo capacity runs 927 to 2,442 lb, so the lightest plan carries more than two and a half times the payload of the heaviest one at almost the same loaded weight. Dry tongue weight runs 600 to 985 lb. For a buyer matching a half-ton truck, this is a line where the tow rating question is nearly settled by the badge and the real decision is how much of it is left for gear.

Water dominates the load plan on this floorplan. Filling the 52-gallon fresh tank consumes about 47% of the 927-pound cargo capacity, which means the 25JT is realistically a travel-with-partial-water trailer unless you are heading somewhere with no hookups and are prepared to leave gear behind.

The published dry tongue weight of 735 pounds is 11% of the 6,808-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Nothing above changes the ceiling. Loaded to its 7,735-pound GVWR the 25JT is towing 927 pounds more than its 6,808-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 52 gallons of fresh against 38 grey and 28 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 25JT sits 3 of 6 in the Campsite Ultra line: 7,735 pounds against a line that runs from 7,600 to 7,985 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Campsite Ultra 26CJL is 61 pounds lighter at 7,674 lb GVWR; and Campsite Ultra 21DF is 60 pounds heavier at 7,795 lb GVWR.

Against the 25JT: the Alpha Wolf 22SW is 3 ft shorter; the Longitude 185RB is 5 lb heavier and 6 ft shorter; the Surveyor Legend 260BHLE is 5 lb heavier. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Campsite Ultra floorplans profiled here run 5,158 to 6,923 pounds dry and 22 to 33 feet of exterior length across 6 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Campsite Ultra line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 11 of them for the 25JT. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: interior height, sleeps, slide count, axle count, tire specification, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (85%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
