2026 East to West Alta3150KBH

The Alta 3150KBH leaves East to West's factory at 8,698 lbs dry with 1,202 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 53-gallon fresh tank spends 440 lbs of the 1,202 lbs before anything else goes in.

Tongue weight is 1,100 lbs, 13% 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: 120 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 Alta roster this is the 15th of 17 floorplans by dry weight, in a line that runs from 3,998 lbs to 10,334 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 8,698 lbs dry figure: half the published cargo capacity brings this plan to about 9,299 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. 3150KBH is a Alta designation and this site does not decode it into a layout claim.

How the 3150KBH differs from the other sixteen Alta floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Cargo capacity, 1,202 lb: smallest of seventeen; next is the 1800MBH-LE (1,311 lb).
• Length, 38 ft 1 in: second-longest of seventeen, between the 3175RK (37 ft 11 in) and the 3250KXT (38 ft 5 in).
• Dry weight, 8,698 lb: third-heaviest of seventeen, between the 2870KTH (8,633 lb) and the 3175RK (9,133 lb).
• Exterior height, 11 ft 5 in: fourth-tallest of seventeen, between the 3010KBH and 3175RK (11 ft 4 in) and the 2400KTH (12 ft 4 in).
• Tongue weight, 1,100 lb: fifth-heaviest of seventeen, between the 3010KBH (1,070 lb) and the 2400KTH (1,165 lb).
• Grey tank, 90 gal: largest of seventeen, level with the 2775KFK and 3175RK; next are the 2375KRK, 2400KTH and eight others (60 gal).
• Tongue weight as a share of dry weight, 12.6%: seventh-largest of seventeen, between the 1600MRB-LE (11.8%) and the 2375KRK (12.7%).

Next to the 2870KTH, the nearest lighter floorplan by dry weight, the 3150KBH is 65 lb heavier by dry weight, has 3,515 lb less cargo capacity, has a tongue weight 250 lb lighter, is 5 ft longer, stands 1 ft lower, has a fresh tank 57 gal smaller and has a grey tank 30 gal larger; the two publish the same black tank.

Next to the 3175RK, the nearest heavier floorplan by dry weight, the 3150KBH is 435 lb lighter by dry weight, has 1,045 lb less cargo capacity, has a tongue weight 80 lb lighter, is 2 in longer, stands 1 in taller and has a fresh tank 2 gal smaller; the two publish the same grey tank and black tank.

Alta is the broadest roster East to West publishes, and the spread is the reason to read the table rather than the floorplan numbers. Sixteen floorplans run from 3,998 lb dry on the single-axle LE plans to 10,334 lb at the top, which is not one trailer class but three: a pair of single-axle LE models, ten mainstream tandem-axle trailers, and two toy haulers plus one Xtreme plan at the heavy end. Crucially all of them are bumper pull. Tongue weight runs 470 to 1,350 lb across the whole roster, and even the toy haulers -- which East to West groups separately -- load 1,165 to 1,350 lb onto a ball, not a pin. That matters because a toy hauler badge usually implies a fifth wheel and here it does not. Cargo capacity runs 1,202 to 4,717 lb.

A full 53-gallon fresh tank is about 440 lb of water, 37% of the 3150KBH’s 1,202 lb cargo capacity, leaving 762 lb. Across 17 Alta floorplans the water share runs 13% to 37%, and this plan’s is the highest. Nearest on that share: Alta 2410KML at 34%.
