2026 Forest River XLR Boost2715B

The XLR Boost 2715B leaves Forest River's factory at 8,393 lbs dry with 5,107 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 5,107 lbs before anything else goes in.

Tongue weight is 1,500 lbs, 18% 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: 120 gallons of grey and black capacity against 102 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the XLR Boost travel-trailer roster this is the 3rd of 4 travel trailers by dry weight, in a line that runs from 6,758 lbs to 9,038 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 8,393 lbs dry figure: half the published cargo capacity brings this plan to about 10,947 lbs. Forest River publishes no loaded rating for this line, so the ceiling is the one on the trailer’s own weight label (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. No GVWR is published for this line, so dry plus cargo has no rating to check against. 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. 2715B is a XLR Boost designation and this site does not decode it into a layout claim.

How the 2715B differs from the other three XLR Boost travel trailers. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Cargo capacity, 5,107 lb: largest of four; next is the 2115B (4,617 lb).
• Tongue weight as a share of dry weight, 17.9%: largest of four; next is the 2115B (17.4%).
• Dry weight, 8,393 lb: second-heaviest of four, between the 2413B (7,328 lb) and the 3012BX (9,038 lb).
• Tongue weight, 1,500 lb: second-heaviest of four, between the 2413B (1,200 lb) and the 3012BX (1,560 lb).
• Length, 34 ft 2 in: second-longest of four, between the 2413B (30 ft) and the 3012BX (37 ft).
• Exterior height, 12 ft 8 in: tallest of four, level with the 3012BX; next are the 2115B and 2413B (12 ft 6 in).

Next to the 2413B, the nearest lighter floorplan by dry weight, the 2715B is 1,065 lb heavier by dry weight, has 1,035 lb more cargo capacity, has a tongue weight 300 lb heavier, is 4 ft 2 in longer and stands 2 in taller; the two publish the same fresh tank, grey tank and black tank.

Next to the 3012BX (2027 page), the nearest heavier floorplan by dry weight, the 2715B is 645 lb lighter by dry weight, has 585 lb more cargo capacity, has a tongue weight 60 lb lighter, is 2 ft 10 in shorter and has a black tank 40 gal smaller; the two publish the same exterior height, fresh tank and grey tank.

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.

A full 102-gallon fresh tank is about 847 lb of water, 17% of the 2715B’s 5,107 lb cargo capacity, leaving 4,260 lb. Across 4 XLR Boost travel-trailer floorplans the water share runs 17% to 21%, and this plan’s is the lowest. Nearest on that share: XLR Boost 2115B at 18%.
