2026 Forest River Campsite Reserve20AJ

The Campsite Reserve 20AJ has 2,857 lbs of cargo capacity between 4,693 lbs dry and its 7,550 lbs GVWR, 38% 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 550 lbs, 12% 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 Reserve roster this is the 5th of 22 floorplans by dry weight, in a line that runs from 3,764 lbs to 12,380 lbs. It sits in the lighter third of the line.

Plan the tow on loaded weight, not the 4,693 lbs dry figure: half the published cargo capacity brings this plan to about 6,121 lbs, and the published GVWR of 7,550 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. 20AJ is a Campsite Reserve designation and this site does not decode it into a layout claim.

How the 20AJ differs from the other 21 Campsite Reserve floorplans. Most distinctive first. How these ranks are worked out.

• Cargo capacity as a share of GVWR, 37.8%: second-largest of 21, between the 23SF (37.4%) and the 20LJ (38.2%).
• GVWR, 7,550 lb: fourth-lowest of 22, between the 17LS (5,625 lb) and the 20LJ (7,580 lb).
• Tongue weight, 550 lb: fourth-lightest of 22, between the 17LS (525 lb) and the 20LJ (580 lb).
• Length, 24 ft 7 in: fourth-shortest of 22, between the 17LS (23 ft 10 in) and the 20LJ (25 ft 9 in).
• Dry weight, 4,693 lb: fifth-lightest of 22, between the 20LJ (4,688 lb) and the 23SF (4,818 lb).
• Cargo capacity, 2,857 lb: sixth-largest of 22, between the 27MR (2,742 lb) and the 23SF (2,882 lb).
• Tongue weight as a share of dry weight, 11.7%: ninth-smallest of 22, between the 16BC and 20JW (11.5%) and the 17LS and 25CY (12.2%).
• Black tank, 28 gal: smallest of 22, level with the 16BC, 17LS and seven others; next are the 20LJ, 26CJ and five others (38 gal).
• Exterior height, 10 ft 8 in: shared with the 23JW, 25CY and three others; of 22, five lower and eleven taller, nearest the 29TJ (10 ft 7 in) and the 18LM (10 ft 9 in).

Next to the 20LJ, the nearest lighter floorplan by dry weight, the 20AJ is 5 lb heavier by dry weight, has a GVWR 30 lb lower, has 35 lb less cargo capacity, has a tongue weight 30 lb lighter, is 1 ft 2 in shorter, stands 2 in taller and has a black tank 10 gal smaller; the two publish the same fresh tank and grey tank.

Next to the 23SF, the nearest heavier floorplan by dry weight, the 20AJ is 125 lb lighter by dry weight, has a GVWR 150 lb lower, has 25 lb less cargo capacity, has a tongue weight 150 lb lighter, is 2 ft 11 in shorter and stands 2 in taller; the two publish the same fresh tank, grey tank and black tank.

Campsite Reserve is the widest single Forest River travel-trailer roster this site carries: dry weight runs 3,764 lb at the 16BC to 12,380 lb at the top of the loft group, and cargo capacity runs 1,020 to 4,336 lb. Tongue weight runs 431 to 1,425 lb and GVWR 5,531 to 14,000 lb. The loft plans are where the weight is -- the 39-series sits at the top of every column -- and the three toy haulers sit in the middle rather than the top, which is unusual for a line that carries both. Twenty-one of the twenty-two profileable plans tie out exactly against dry weight plus cargo capacity. The exception is 23TS, whose own arithmetic gives 7,795 lb against a published GVWR of 7,805; it is published on its own page with that disagreement stated rather than profiled with the rest.

A full 52-gallon fresh tank is about 432 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 15% of the 20AJ’s 2,857 lb cargo capacity, leaving 2,425 lb. Across 22 Campsite Reserve floorplans the water share runs 8% to 34%, and 14 give up more than this one. Nearest on that share: Campsite Reserve 23SF at 15% and Campsite Reserve 27MR at 16%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
