2026 Forest River Campsite Ultra25JT

The Campsite Ultra 25JT has 927 lbs of cargo capacity between 6,808 lbs dry and its 7,735 lbs GVWR, 12% of that rating; filling its 52-gallon fresh tank at 8.3 lb a gallon uses 432 lbs of it (how to read trailer weights).

Tongue weight is 735 lbs, 11% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).

Off hookups: 66 gallons of grey and black capacity against 52 gallons of fresh water, so fresh water runs out first (tank sizes by length).

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.

Plan the tow on loaded weight, not the 6,808 lbs dry figure: half the published cargo capacity brings this plan to about 7,272 lbs, and the published GVWR of 7,735 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. A missing row means Forest River does not publish that figure (how figures are verified).

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.

How the 25JT differs from the other five Campsite Ultra floorplans. Most distinctive first. How these ranks are worked out.

• Cargo capacity, 927 lb: smallest of six; next is the 26BW (1,062 lb).
• Cargo capacity as a share of GVWR, 12%: smallest of six; next is the 26BW (13.3%).
• Dry weight, 6,808 lb: second-heaviest of six, between the 26TH (6,513 lb) and the 26BW (6,923 lb).
• Tongue weight as a share of dry weight, 10.8%: second-smallest of six, between the 26CJL (10.5%) and the 19KB (11.6%).
• GVWR, 7,735 lb: third-lowest of six, between the 26CJL (7,674 lb) and the 21DF (7,795 lb).
• Tongue weight, 735 lb: third-lightest of six, between the 26CJL (674 lb) and the 21DF (795 lb).
• Length, 30 ft 1 in: third-shortest of six, between the 21DF (25 ft 10 in) and the 26BW (30 ft 3 in).
• Black tank, 28 gal: smallest of six, level with the 19KB and 21DF; next are the 26BW and 26CJL (38 gal).
• Exterior height, 10 ft 7 in: shared with the 19KB and 26CJL; of six, one lower and two taller, nearest the 21DF (10 ft 6 in) and the 26BW and 26TH (10 ft 8 in).

Next to the 26TH, the nearest lighter floorplan by dry weight, the 25JT is 295 lb heavier by dry weight, has a GVWR 85 lb lower, has 380 lb less cargo capacity, has a tongue weight 85 lb lighter, is 8 in shorter, stands 1 in lower and has a black tank 28 gal smaller; the two publish the same fresh tank and grey tank.

Next to the 26BW, the nearest heavier floorplan by dry weight, the 25JT is 115 lb lighter by dry weight, has a GVWR 250 lb lower, has 135 lb less cargo capacity, has a tongue weight 250 lb lighter, is 2 in shorter, stands 1 in lower and has a black tank 10 gal smaller; the two publish the same fresh tank and grey tank.

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. Tongue weight runs 600 to 985 lb. For a buyer, the real decision on this line is how much of the tow vehicle’s rating is left for gear.

A full 52-gallon fresh tank is about 432 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 47% of the 25JT’s 927 lb cargo capacity, leaving 495 lb. Across 6 Campsite Ultra floorplans the water share runs 18% to 47%, and this plan’s is the highest. Nearest on that share: Campsite Ultra 26BW at 41%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
