2026 Forest River XLR Nitro40BAR13

The XLR Nitro 40BAR13 leaves Forest River's factory at 16,949 lbs dry with 4,051 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 150-gallon fresh tank spends 1,245 lbs of the 4,051 lbs before anything else goes in.

Pin weight is 3,480 lbs, 21% of the dry weight as published; it rises as the trailer is loaded and comes off the truck’s payload, not its towing rating, so check it against the payload on your own door sticker (pin weight and payload).

Off hookups: 155 gallons of grey and black capacity against 150 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the XLR Nitro roster this is the 5th of 5 floorplans by dry weight, in a line that runs from 13,124 lbs to 16,949 lbs. It is the heaviest plan in the line, so the tow vehicle should be settled before the floorplan is.

Plan the tow on loaded weight, not the 16,949 lbs dry figure: half the published cargo capacity brings this plan to about 18,975 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. 40BAR13 is a XLR Nitro designation and this site does not decode it into a layout claim.

How the 40BAR13 differs from the other four XLR Nitro floorplans. Most distinctive first. How these ranks are worked out.

• Dry weight, 16,949 lb: heaviest of five; next is the 41G14 (15,679 lb).
• Length, 45 ft 6 in: longest of five; next is the 41G14 (45 ft 1 in).
• Exterior height, 13 ft 4 in: lowest of five; next are the 32W17, 35G13 and two others (13 ft 6 in).
• Grey tank, 123 gal: largest of five; next are the 32W17, 35G13 and two others (120 gal).
• Black tank, 32 gal: smallest of five; next is the 32W17 (40 gal).
• Pin weight, 3,480 lb: second-heaviest of five, between the 35G13 (3,250 lb) and the 40G17 (3,765 lb).
• Pin weight as a share of dry weight, 20.5%: second-smallest of five, between the 41G14 (20.3%) and the 35G13 (23.3%).
• Cargo capacity, 4,051 lb: third-smallest of five, between the 32W17 (4,036 lb) and the 41G14 (5,321 lb).

Next to the 41G14, the nearest lighter floorplan by dry weight, the 40BAR13 is 1,270 lb heavier by dry weight, has 1,270 lb less cargo capacity, has a pin weight 290 lb heavier, is 5 in longer, stands 2 in lower, has a grey tank 3 gal larger and has a black tank 48 gal smaller; the two publish the same fresh tank.

XLR Nitro is the heaviest line in this group: five published floorplans from 13,124 to 16,949 lb dry, on pin weights of 3,160 to 3,765 lb. A pin weight in that band comes off the truck's payload before anyone loads the garage, and cargo capacity runs 3,281 to 5,326 lb on top of it. Forest River publishes no GVWR for any Nitro floorplan, so the rating a buyer needs to check against is not in the factory's own spec channel.

A full 150-gallon fresh tank is about 1,245 lb of water, 31% of the 40BAR13’s 4,051 lb cargo capacity, leaving 2,806 lb. Across 5 XLR Nitro floorplans the water share runs 23% to 38%, and 2 give up more than this one. Nearest on that share: XLR Nitro 41G14 at 23% and XLR Nitro 32W17 at 31%.
