2026 Forest River XLR Boost286B

The XLR Boost 286B leaves Forest River's factory at 9,094 lbs dry with 5,000 lbs of cargo capacity. Forest River publishes no GVWR for this line, so the loaded rating is not quoted on this page and is not computed from the other two figures. What the cargo number covers is defined by the factory: fresh water, gear, food, batteries and every dealer-installed accessory come out of it. Fresh water is 8.3 lb per gallon, so filling the 102-gallon fresh tank spends 847 lbs of the 5,000 lbs before anything else goes in.

Dry pin weight is 2,090 lbs, which is 23% of the dry weight. That figure lands on the truck's rear axle and comes straight off its payload rating - not its towing rating, which is the number most often quoted and the wrong one for this decision. Pin weight rises as the trailer is loaded, and a fifth wheel loaded toward its cargo capacity will put substantially more than 2,090 lbs over the bed. Read the payload figure on your own door sticker rather than a brochure maximum for the model.

Tank capacities are 102 gallons fresh, 108 grey and 32 black, 140 gallons of waste capacity against 102 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 XLR Boost roster this is the 8th of 11 floorplans by dry weight, in a line that runs from 6,473 lbs to 13,074 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 these figures is to stop planning against the dry weight. Nobody tows a trailer at 9,094 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity and this plan is already near 11,594 lbs on the road. Because Forest River publishes no loaded rating for this line, the ceiling has to come from the trailer's own weight label rather than from this page, and the comparison you make against the tow vehicle should use the loaded figure.

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. There is no published GVWR on this line, so the usual arithmetic check - dry plus cargo equals the rating - has nothing to test against here. 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. 286B is a XLR Boost designation and this site does not decode it into a layout claim.

XLR Boost is the hardest of Forest River's toy-hauler rosters to read from the outside, for two reasons. It mixes classes: three published floorplans are XLR Boost travel trailers at 6,758 to 8,393 lb dry with 1,175 to 1,500 lb on the tongue, and three are XLR Boost or XLR Boost X fifth wheels at 9,094 to 13,074 lb dry with 2,090 to 3,220 lb on the pin. And Forest River publishes no GVWR for any of the eleven plans, so the loaded figure that determines whether a given truck can legally tow a given plan is not available from the factory in this channel. Cargo capacity is published, 2,507 to 5,300 lb, and dry weight is published, so what the roster tells you is what the trailer weighs empty and how much it will carry - not what it may weigh when full.

This floorplan carries its water comfortably. A full 102-gallon fresh tank is roughly 17% of the 5,000-pound cargo capacity, leaving the 286B with a usable gear budget even when you tow full.

The published dry pin weight of 2,090 pounds is 23% of this floorplan’s 9,094-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Tank balance is generous here: 102 gallons of fresh against 108 grey and 32 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by dry weight, the 286B sits 4 of 6 in the XLR Boost line: 9,094 pounds against a line that runs from 6,758 to 13,074 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: XLR Boost 2715B is 701 pounds lighter at 8,393 lb dry; and XLR Boost 363BX is 2,970 pounds heavier at 12,064 lb dry.

Against the 286B: the Reflection 298BH is 44 lb lighter and 3 ft longer; the Cougar 26RKE is 106 lb heavier; the Wolf Pack 275PACK15 is 219 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 fifth wheels 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 XLR Boost floorplans profiled here run 6,758 to 13,074 pounds dry and 28 to 44 feet of exterior length across 6 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 XLR Boost line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 10 of them for the 286B. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: GVWR, interior height, sleeps, slide count, axle count, tire specification, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (83%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
