2027 Forest River Airelume170

The Airelume 170 leaves Forest River's factory at 4,084 lbs dry, with a published GVWR of 5,550 lbs and 1,466 lbs of cargo capacity between the two. Cargo capacity is 26% 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 39-gallon fresh tank spends 324 lbs of that 1,466 lbs before anything else is loaded.

Tongue weight is 450 lbs, 11% 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: 60 gallons of grey and black capacity against 39 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Airelume roster this is the 5th of 12 floorplans by dry weight, in a line that runs from 2,824 lbs to 8,708 lbs. It sits in the middle of the line by weight.

Plan the tow on loaded weight, not the 4,084 lbs dry figure: half the published cargo capacity brings this plan to about 4,817 lbs, and the published GVWR of 5,550 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. 170 is a Airelume designation and this site does not decode it into a layout claim.

How the 170 differs from the other eleven Airelume floorplans. Most distinctive first. How these ranks are worked out.

• Cargo capacity as a share of GVWR, 26.4%: third-largest of twelve, between the 162 (26.2%) and the 260 (31.3%).
• Tongue weight, 450 lb: third-lightest of twelve, between the 160 (425 lb) and the 172 (460 lb).
• GVWR, 5,550 lb: fourth-lowest of twelve, between the 172 (4,860 lb) and the 232 (6,054 lb).
• Length, 23 ft 9 in: fourth-shortest of twelve, between the 160 (21 ft 8 in) and the 232 (27 ft 3 in).
• Dry weight, 4,084 lb: fifth-lightest of twelve, between the 232 (4,054 lb) and the 260 (4,399 lb).
• Cargo capacity, 1,466 lb: fifth-smallest of twelve, between the 265 (1,442 lb) and the 255 (1,972 lb).
• Tongue weight as a share of dry weight, 11%: smallest of twelve, level with the 260; next is the 162 (11.5%).
• Exterior height, 10 ft 5 in: fifth-lowest of twelve, between the 172 and 255 (10 ft 4 in) and the 260 (10 ft 7 in).
• Fresh tank, 39 gal: smallest of twelve, level with the 160, 162 and three others; next are the 255, 270 and three others (40 gal).

Next to the 232, the nearest lighter floorplan by dry weight, the 170 is 30 lb heavier by dry weight, has a GVWR 504 lb lower, has 534 lb less cargo capacity, has a tongue weight 80 lb lighter, is 3 ft 6 in shorter and stands 3 in lower; the two publish the same fresh tank, grey tank and black tank.

Next to the 260, the nearest heavier floorplan by dry weight, the 170 is 315 lb lighter by dry weight, has a GVWR 849 lb lower, has 534 lb less cargo capacity, has a tongue weight 35 lb lighter, is 4 ft 10 in shorter and stands 2 in lower; the two publish the same fresh tank, grey 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 39-gallon fresh tank is about 324 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 22% of the 170’s 1,466 lb cargo capacity, leaving 1,142 lb. Across 12 Airelume floorplans the water share runs 16% to 38%, and 4 give up more than this one. Nearest on that share: Airelume 255 at 17% and Airelume 265 at 25%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
