2027 Forest River Airelume315

The Airelume 315 leaves Forest River's factory at 8,708 lbs dry, with a published GVWR of 10,708 lbs and 2,000 lbs of cargo capacity between the two. Cargo capacity is 19% 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 40-gallon fresh tank spends 332 lbs of that 2,000 lbs before anything else is loaded.

Tongue weight is 1,040 lbs, 12% 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: 73 gallons of grey and black capacity against 40 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Airelume roster this is the 12th of 12 floorplans by dry weight, in a line that runs from 2,824 lbs to 8,708 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 8,708 lbs dry figure: half the published cargo capacity brings this plan to about 9,708 lbs, and the published GVWR of 10,708 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. 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. 315 is a Airelume designation and this site does not decode it into a layout claim.

How the 315 differs from the other eleven Airelume floorplans. Most distinctive first. How these ranks are worked out.

• Dry weight, 8,708 lb: heaviest of twelve; next is the 325 (7,813 lb).
• GVWR, 10,708 lb: highest of twelve; next is the 325 (9,813 lb).
• Length, 37 ft 2 in: longest of twelve; next is the 325 (36 ft 11 in).
• Exterior height, 11 ft 5 in: tallest of twelve; next is the 325 (11 ft 4 in).
• Cargo capacity as a share of GVWR, 18.7%: second-smallest of twelve, between the 265 (18.4%) and the 325 (20.4%).
• Tongue weight, 1,040 lb: second-heaviest of twelve, between the 285 (895 lb) and the 325 (1,090 lb).
• Tongue weight as a share of dry weight, 11.9%: fourth-smallest of twelve, between the 162 (11.5%) and the 285 (12.4%).
• Grey tank, 43 gal: fifth-largest of twelve, between the 160, 162 and five others (30 gal) and the 265, 270 and two others (60 gal).
• Cargo capacity, 2,000 lb: largest of twelve, level with the 232, 260 and three others; next is the 255 (1,972 lb).
• Fresh tank, 40 gal: shared with the 255, 270 and two others; of twelve, six smaller and one larger, nearest the 160, 162 and four others (39 gal) and the 265 (44 gal).

Next to the 325, the nearest lighter floorplan by dry weight, the 315 is 895 lb heavier by dry weight, has a GVWR 895 lb higher, has a tongue weight 50 lb lighter, is 3 in longer, stands 1 in taller and has a grey tank 17 gal smaller; the two publish the same cargo capacity, fresh tank and black tank.

Airelume is a wide line for a single grouping: dry weight runs 2,824 lb at the 160 up to 8,708 lb at the 325, so the heaviest plan is more than three times the lightest. Cargo capacity runs 856 to 2,000 lb and tongue weight 325 to 1,090 lb. GVWR runs 3,825 to 10,708 lb. Because every plan publishes a factory GVWR that ties out, the loaded rating on this line is a measured number on every page rather than a reconstruction.

A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 17% of the 315’s 2,000 lb cargo capacity, leaving 1,668 lb. Across 12 Airelume floorplans the water share runs 16% to 38%, and 6 give up more than this one. Nearest on that share: Airelume 270 at 17% and Airelume 255 at 17%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
