2026 East to West Longitude310RL

The Longitude 310RL leaves East to West's factory at 7,708 lbs dry, with a published GVWR of 11,280 lbs and 3,572 lbs of cargo capacity between the two. Cargo capacity is 32% of the loaded rating, and East to West'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 53-gallon fresh tank spends 440 lbs of that 3,572 lbs before anything else is loaded.

Tongue weight is 880 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: 90 gallons of grey and black capacity against 53 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Longitude roster this is the 6th of 8 floorplans by dry weight, in a line that runs from 5,293 lbs to 8,033 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 7,708 lbs dry figure: half the published cargo capacity brings this plan to about 9,494 lbs, and the published GVWR of 11,280 lbs is the limit (how to read trailer weights).

East to West’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 East to West does not publish that figure (how figures are verified).

East to West 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. 310RL is a Longitude designation and this site does not decode it into a layout claim.

How the 310RL differs from the other seven Longitude floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Cargo capacity, 3,572 lb: largest of eight; next is the 319BH (3,547 lb).
• GVWR, 11,280 lb: second-highest of eight, between the 285BH (9,680 lb) and the 319BH (11,335 lb).
• Cargo capacity as a share of GVWR, 31.7%: second-largest of eight, between the 185RB (31.6%) and the 230FK (36.5%).
• Dry weight, 7,708 lb: third-heaviest of eight, between the 285BH (7,628 lb) and the 319BH (7,788 lb).
• Tongue weight as a share of dry weight, 11.4%: third-smallest of eight, between the 255BH (10.7%) and the 285BH (11.5%).
• Length, 35 ft 10 in: third-longest of eight, between the 285BH (33 ft 9 in) and the 315FB (35 ft 11 in).
• Tongue weight, 880 lb: shared with the 285BH; of eight, five lighter and one heavier, nearest the 315FB (840 lb) and the 319BH (935 lb).

Next to the 285BH, the nearest lighter floorplan by dry weight, the 310RL is 80 lb heavier by dry weight, has a GVWR 1,600 lb higher, has 1,520 lb more cargo capacity and is 2 ft 1 in longer; the two publish the same tongue weight, exterior height, fresh tank, grey tank and black tank.

Next to the 319BH, the nearest heavier floorplan by dry weight, the 310RL is 80 lb lighter by dry weight, has a GVWR 55 lb lower, has 25 lb more cargo capacity, has a tongue weight 55 lb lighter and is 2 ft 3 in shorter; the two publish the same exterior height, fresh tank, grey tank and black tank.

Longitude is the only East to West line on this site that publishes a GVWR, and it is worth saying plainly what that buys you: on all seven plans where East to West publishes one, dry weight plus cargo capacity equals the published GVWR exactly. That arithmetic tying out is the difference between a loaded rating you can plan a tow around and a number somebody added up. GVWR runs 7,650 to 11,335 lb across the seven, against dry weights of 5,293 to 8,033 lb and cargo capacity of 1,367 to 3,572 lb. Tongue weight runs 650 to 935 lb, all bumper pull. Three more floorplans are published on the roster with no weights at all yet, and they are listed as announced rather than given specifications they do not have.

A full 53-gallon fresh tank is about 440 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 12% of the 310RL’s 3,572 lb cargo capacity, leaving 3,132 lb. Across 8 Longitude floorplans the water share runs 12% to 28%, and this plan’s is the lowest. Nearest on that share: Longitude 319BH at 12%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
