01 What makes it unique
The XLR Boost 3012BX leaves Forest River's factory at 9,038 lbs dry with 4,522 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 4,522 lbs before anything else goes in.
Tongue weight is 1,560 lbs, or 17% 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 102 gallons fresh, 80 grey and 80 black, 160 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 travel-trailer roster this is the 4th of 4 travel trailers by dry weight, in a line that runs from 6,758 lbs to 9,038 lbs. It is the heaviest travel trailer in the line, so the tow vehicle should be settled before the floorplan is. 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 9,038 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 11,299 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 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. 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. 3012BX is a XLR Boost designation and this site does not decode it into a layout claim.
How the 3012BX differs from the other three XLR Boost travel trailers. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out. Not every one of these pages covers the same model years as this one (2027); each figure is the one its own page prints, so a rank compares pages, not one model year.
- Dry weight, 9,038 lb: heaviest of four; next is the 2715B (8,393 lb).
- Tongue weight, 1,560 lb: heaviest of four; next is the 2715B (1,500 lb).
- Length, 37 ft: longest of four; next is the 2715B (34 ft 2 in).
- Black tank, 80 gal: largest of four; next are the 2115B, 2413B and 2715B (40 gal).
- Cargo capacity, 4,522 lb: second-smallest of four, between the 2413B (4,072 lb) and the 2115B (4,617 lb).
- Tongue weight as a share of dry weight, 17.3%: second-smallest of four, between the 2413B (16.4%) and the 2115B (17.4%).
- Exterior height, 12 ft 8 in: tallest of four, level with the 2715B; next are the 2115B and 2413B (12 ft 6 in).
Next to the 2715B (2026 page), the nearest lighter floorplan by dry weight, the 3012BX is 645 lb heavier by dry weight, has 585 lb less cargo capacity, has a tongue weight 60 lb heavier, is 2 ft 10 in longer and has a black tank 40 gal larger; the two publish the same exterior height, fresh tank and grey tank.

03 The XLR Boost floorplan family
Eight 2027 XLR Boost floorplans with a full factory record. They run 6,758 to 13,074 lb dry on lengths of 28 feet 6 inches to 45 feet 3 inches, with hitch weights of 1,175 to 3,220 lb and cargo capacities of 4,072 to 5,300 lb. Forest River publishes no GVWR for these plans in this channel, so none is shown and none is computed.

Six of these eight 2027 plans were also on the 2026 roster and keep their 2026 pages, each with its 2027 record shown separately; 3012BX, 375BX are new for 2027. Eight further roster entries are listed on the hub without a page. Sleeping capacity, axle count, tire size and MSRP are not published in this channel.
04 Notes on this floorplan
What Forest River does not publish for this line
Sleeping capacity, axle count, tire size and MSRP are absent from Forest River's specification channel for XLR Boost, so they are absent here. They are not estimated from the segment, not carried over from a sibling floorplan, and not taken from a dealer listing quoting itself. A tire size in particular is a safety-relevant number that differs between two codes a digit apart, and this site does not guess one.
There is no factory GVWR for this trailer
Forest River publishes dry weight, cargo capacity and tongue weight for every XLR Boost floorplan and publishes no GVWR for any of them. The factory's own glossary defines cargo capacity as GVWR minus UVW, which means the rating can be worked out - and a figure you worked out is not a figure the manufacturer published, so this page does not print one. Use the weight label on the trailer itself, which every Forest River unit carries.
Weigh it before you tow it
Every figure on this page is a factory publication for a standard build. Forest River's own footnote on unloaded weight calls it an estimated average based on a standard build with optional equipment, and options, dealer-installed accessories and the previous owner's additions all move it. The only weight that governs your towing decision is the one under your own trailer on a scale, loaded the way you actually travel.
05 How it compares
8,393 lbs dry against this plan's 9,038 lbs, a difference of 645 lbs. Same line, same factory channel, same model year - so the gap is a real one rather than a difference in how two brands measure.
9,524 lbs dry, 486 lbs more than this plan, and 5,300 lbs of cargo capacity against this one's 4,522 lbs. Stepping up a floorplan usually buys length before it buys payload.
5,107 lbs of cargo capacity, the highest of the 4 XLR Boost travel trailers profiled here. If payload rather than length is the binding constraint, that is the plan to compare against.
06 Loading it for a trip
A full 102-gallon fresh tank is about 847 lb of water, 19% of the 3012BX’s 4,522 lb cargo capacity, leaving 3,675 lb. Across 4 XLR Boost travel-trailer floorplans the water share runs 17% to 21%, and 1 gives up more than this one. Nearest on that share: XLR Boost 2115B at 18% and XLR Boost 2413B at 21%.
07 Where this floorplan sits
Closest sibling: the XLR Boost 2715B, nearest on the published figures. It differs on 5 of the 7 fields both publish (this plan first): length 37 ft 0 in vs 34 ft 2 in; dry weight 9,038 lb vs 8,393 lb; cargo capacity 4,522 lb vs 5,107 lb; hitch weight 1,560 lb vs 1,500 lb; black tank 80 gal vs 40 gal. They match on fresh tank and grey tank.
