2026 Forest River Campsite Reserve39LA

The Campsite Reserve 39LA leaves Forest River's factory at 12,194 lbs dry, with a published GVWR of 14,000 lbs and 1,806 lbs of cargo capacity between the two. Cargo capacity is 13% 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 40-gallon fresh tank spends 332 lbs of that 1,806 lbs before anything else is loaded.

Dry tongue weight is 1,305 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 40 gallons fresh, 70 grey and 40 black, 110 gallons of waste capacity against 40 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 Reserve roster this is the 21st 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. 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 12,194 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 13,097 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 14,000 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 listing 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. 39LA is a Campsite Reserve designation and this site does not decode it into a layout claim.

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. Dry 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 catalogued here with that disagreement stated and is not profiled.

A full 40-gallon fresh tank is about 334 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 18% of the 39LA’s 1,806 lb cargo capacity, leaving 1,472 lb. Across 21 Campsite Reserve floorplans the water share runs 8% to 35%, and 6 give up more than this one. Nearest on that share: Campsite Reserve 32GT at 18% and Campsite Reserve 18LM at 20%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

Closest sibling: the Campsite Reserve 39JD, nearest on the published figures. It differs on 7 of the 8 fields both publish (this plan first): length 43 ft 9 in vs 43 ft 4 in; dry weight 12,194 lb vs 12,380 lb; GVWR 14,000 lb vs 13,400 lb; cargo capacity 1,806 lb vs 1,020 lb; dry hitch weight 1,305 lb vs 1,400 lb; grey tank 70 gal vs 80 gal; black tank 40 gal vs 80 gal. They match on fresh tank.

Either side of it by GVWR: Campsite Reserve 39IB matches it at 14,000 lb GVWR.
