2026 Forest River Campsite Reserve28SW

The Campsite Reserve 28SW leaves Forest River's factory at 7,578 lbs dry, with a published GVWR of 11,625 lbs and 4,047 lbs of cargo capacity between the two. Cargo capacity is 35% 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 52-gallon fresh tank spends 432 lbs of that 4,047 lbs before anything else is loaded.

Dry tongue weight is 1,425 lbs, or 19% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits above 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 52 gallons fresh, 38 grey and 38 black, 76 gallons of waste capacity against 52 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 16th 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 7,578 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 9,602 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 11,625 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 roster block 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. 28SW 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.

This floorplan carries its water comfortably. A full 52-gallon fresh tank is roughly 11% of the 4,047-pound cargo capacity, leaving the 28SW with a usable gear budget even when you tow full.

The published dry tongue weight of 1,425 pounds is 19% of the 7,578-pound dry weight — at or above the top of the usual 10–15% band before you load anything. A nose-heavy dry figure eats truck payload directly, so budget the hitch load against your door-jamb sticker rather than against the tow rating.

Nothing above changes the ceiling. Loaded to its 11,625-pound GVWR the 28SW is towing 4,047 pounds more than its 7,578-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 52 gallons of fresh against 38 grey and 38 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 28SW sits 17 of 21 in the Campsite Reserve line: 11,625 pounds against a line that runs from 5,531 to 14,000 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Campsite Reserve 20JW is 420 pounds lighter at 11,205 lb GVWR; and Campsite Reserve 39GB is 1,630 pounds heavier at 13,255 lb GVWR.

Against the 28SW: the Vengeance Rogue 28SUT is 20 lb heavier and 3 ft shorter; the Aurora Destination Series 40BHTS is 43 lb lighter and 3 ft longer; the Wolf Pack 27-12.5 is 65 lb heavier. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Campsite Reserve floorplans profiled here run 3,764 to 12,380 pounds dry and 22 to 44 feet of exterior length across 21 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Campsite Reserve line hub.

Named sources publish 11 of the 18 specification fields this catalogue tracks for the 28SW (85% complete on the full field set).
