2026 East to West Ahara390DS

The Ahara 390DS leaves East to West's factory at 15,664 lbs dry with 3,451 lbs of cargo capacity. East to West 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 64-gallon fresh tank spends 531 lbs of the 3,451 lbs before anything else goes in.

Pin weight is 3,115 lbs, 20% 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: 220 gallons of grey and black capacity against 64 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Ahara roster this is the 7th of 8 floorplans by dry weight, in a line that runs from 12,064 lbs to 15,794 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 15,664 lbs dry figure: half the published cargo capacity brings this plan to about 17,390 lbs. East to West 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).

East to West’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 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. 390DS is a Ahara designation and this site does not decode it into a layout claim.

How the 390DS differs from the other seven Ahara floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Dry weight, 15,664 lb: second-heaviest of eight, between the 385DS (15,009 lb) and the 395FB (15,794 lb).
• Pin weight, 3,115 lb: second-heaviest of eight, between the 385DS (2,820 lb) and the 380FL (3,220 lb).
• Pin weight as a share of dry weight, 19.9%: second-largest of eight, between the 383UR (19.2%) and the 380FL (21.7%).
• Length, 42 ft 10 in: third-longest of eight, between the 383UR (41 ft 4 in) and the 385DS (43 ft 9 in).
• Cargo capacity, 3,451 lb: fourth-smallest of eight, between the 365RL (3,321 lb) and the 297MK (3,746 lb).
• Exterior height, 13 ft 4 in: shared with the 382LK; of eight, four lower and two taller, nearest the 383UR and 395FB (13 ft 3 in) and the 380FL and 385DS (13 ft 5 in).
• Grey tank, 132 gal: largest of eight, level with the 383UR, 385DS and 395FB; next are the 297MK, 365RL and two others (88 gal).
• Black tank, 88 gal: largest of eight, level with the 380FL, 385DS and 395FB; next are the 297MK, 365RL and two others (44 gal).

Next to the 385DS, the nearest lighter floorplan by dry weight, the 390DS is 655 lb heavier by dry weight, has 360 lb less cargo capacity, has a pin weight 295 lb heavier, is 11 in shorter and stands 1 in lower; the two publish the same fresh tank, grey tank and black tank.

Next to the 395FB, the nearest heavier floorplan by dry weight, the 390DS is 130 lb lighter by dry weight, has 435 lb more cargo capacity, has a pin weight 305 lb heavier, is 1 ft 3 in shorter and stands 1 in taller; the two publish the same fresh tank, grey tank and black tank.

Ahara is East to West's full-size fifth wheel, and it is a truck decision before it is a floorplan decision. Nine floorplans run 11,759 to 15,794 lb dry across 34ft 5in to 44ft 1in of exterior length, and the pin loads run 2,310 to 3,220 lb on the seven profiled plans. Pin weight is the number to read first, because unlike a tongue load it sits directly on the tow vehicle's payload rating rather than being partly carried by the trailer's own axles -- and 3,220 lb of pin comes off that payload before any passengers or gear are added. Cargo capacity runs 2,731 to 4,401 lb. Two further plans are sold dealer stock only and are catalogued rather than profiled.

A full 64-gallon fresh tank is about 531 lb of water, 15% of the 390DS’s 3,451 lb cargo capacity, leaving 2,920 lb. Across 8 Ahara floorplans the water share runs 12% to 19%, and 3 give up more than this one. Nearest on that share: Ahara 297MK at 14% and Ahara 365RL at 16%.
