2026 Forest River Campsite Reserve20LJ

The Campsite Reserve 20LJ has 2,892 lbs of cargo capacity between 4,688 lbs dry and its 7,580 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 580 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: 76 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 4th 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 4,688 lbs dry figure: half the published cargo capacity brings this plan to about 6,134 lbs, and the published GVWR of 7,580 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. 20LJ is a Campsite Reserve designation and this site does not decode it into a layout claim.

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

• Cargo capacity as a share of GVWR, 38.2%: largest of 21; next is the 20AJ (37.8%).
• Dry weight, 4,688 lb: fourth-lightest of 22, between the 18LM (4,504 lb) and the 20AJ (4,693 lb).
• Cargo capacity, 2,892 lb: fourth-largest of 22, between the 23SF (2,882 lb) and the 39IB (2,961 lb).
• GVWR, 7,580 lb: fifth-lowest of 22, between the 20AJ (7,550 lb) and the 25CY (7,630 lb).
• Tongue weight, 580 lb: fifth-lightest of 22, between the 20AJ (550 lb) and the 25CY (630 lb).
• Length, 25 ft 9 in: fifth-shortest of 22, between the 20AJ (24 ft 7 in) and the 19KR (26 ft).
• Exterior height, 10 ft 6 in: lowest of 22, level with the 23SF, 25MW and 26CJ; next is the 29TJ (10 ft 7 in).
• Tongue weight as a share of dry weight, 12.4%: eleventh-largest of 22, between the 17LS and 25CY (12.2%) and the 25MW (12.7%).
• Black tank, 38 gal: shared with the 26CJ, 26RM and four others; of 22, ten smaller and five larger, nearest the 16BC, 17LS and eight others (28 gal) and the 20JW, 39GB and 39LA (40 gal).

Next to the 18LM, the nearest lighter floorplan by dry weight, the 20LJ is 184 lb heavier by dry weight, has a GVWR 1,985 lb higher, has 1,801 lb more cargo capacity, has a tongue weight 85 lb heavier, is 2 ft longer, stands 3 in lower, has a fresh tank 26 gal larger, has a grey tank 10 gal larger and has a black tank 10 gal larger.

Next to the 20AJ, the nearest heavier floorplan by dry weight, the 20LJ is 5 lb lighter by dry weight, has a GVWR 30 lb higher, has 35 lb more cargo capacity, has a tongue weight 30 lb heavier, is 1 ft 2 in longer, stands 2 in lower and has a black tank 10 gal larger; the two publish the same fresh tank and grey 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 20LJ’s 2,892 lb cargo capacity, leaving 2,460 lb. Across 22 Campsite Reserve floorplans the water share runs 8% to 34%, and 16 give up more than this one. Nearest on that share: Campsite Reserve 20JW at 14% and Campsite Reserve 23SF at 15%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
