2026 Forest River Campsite Reserve20JW

The Campsite Reserve 20JW has 2,431 lbs of cargo capacity between 8,774 lbs dry and its 11,205 lbs GVWR, 22% of that rating; filling its 40-gallon fresh tank at 8.3 lb a gallon uses 332 lbs of it (how to read trailer weights).

Tongue weight is 1,005 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: 80 gallons of grey and black capacity against 40 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 18th of 22 floorplans by dry weight, in a line that runs from 3,764 lbs to 12,380 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 8,774 lbs dry figure: half the published cargo capacity brings this plan to about 9,990 lbs, and the published GVWR of 11,205 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. 20JW is a Campsite Reserve designation and this site does not decode it into a layout claim.

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

• Dry weight, 8,774 lb: fifth-heaviest of 22, between the 32GT (7,593 lb) and the 39GB (8,919 lb).
• GVWR, 11,205 lb: sixth-highest of 22, between the 29TJ and 32GT (9,995 lb) and the 28SW (11,625 lb).
• Exterior height, 13 ft 6 in: tallest of 22, level with the 39JD and 39LA; next is the 39GB (12 ft 9 in).
• Cargo capacity as a share of GVWR, 21.7%: seventh-smallest of 21, between the 39IB (21.1%) and the 25MW (22.6%).
• Tongue weight, 1,005 lb: seventh-heaviest of 22, between the 29TJ (960 lb) and the 39IB (1,100 lb).
• Length, 35 ft 8 in: eighth-longest of 22, between the 27MR (34 ft 8 in) and the 29TJ (36 ft 11 in).
• Grey tank, 40 gal: shared with the 39GB; of 22, seventeen smaller and three larger, nearest the 19KR, 20AJ and eleven others (38 gal) and the 39LA (70 gal).
• Black tank, 40 gal: shared with the 39GB and 39LA; of 22, seventeen smaller and two larger, nearest the 20LJ, 26CJ and five others (38 gal) and the 39IB (70 gal).
• Cargo capacity, 2,431 lb: eleventh-largest of 22, between the 23TS and 32GT (2,402 lb) and the 25CY (2,452 lb).
• Tongue weight as a share of dry weight, 11.5%: shared with the 16BC; of 22, six smaller and fourteen larger, nearest the 39JD (11.3%) and the 20AJ (11.7%).
• Fresh tank, 40 gal: shared with the 39GB, 39IB and two others; of 22, three smaller and fourteen larger, nearest the 16BC, 17LS and 18LM (26 gal) and the 19KR, 20AJ and twelve others (52 gal).

Next to the 32GT, the nearest lighter floorplan by dry weight, the 20JW is 1,181 lb heavier by dry weight, has a GVWR 1,210 lb higher, has 29 lb more cargo capacity, has a tongue weight 115 lb lighter, is 4 ft 2 in shorter, stands 2 ft 10 in taller, has a fresh tank 12 gal smaller, has a grey tank 2 gal larger and has a black tank 2 gal larger.

Next to the 39GB, the nearest heavier floorplan by dry weight, the 20JW is 145 lb lighter by dry weight, has a GVWR 2,050 lb lower, has 1,905 lb less cargo capacity, has a tongue weight 250 lb lighter, is 4 ft 11 in shorter and stands 9 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 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 14% of the 20JW’s 2,431 lb cargo capacity, leaving 2,099 lb. Across 22 Campsite Reserve floorplans the water share runs 8% to 34%, and 17 give up more than this one. Nearest on that share: Campsite Reserve 16BC at 12% and Campsite Reserve 20LJ at 15%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
