2026 East to West Alta1600MRB-LE

The Alta 1600MRB-LE leaves East to West's factory at 3,998 lbs dry with 1,672 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 46-gallon fresh tank spends 382 lbs of the 1,672 lbs before anything else goes in.

Tongue weight is 470 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: 60 gallons of grey and black capacity against 46 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Alta roster this is the 1st of 17 floorplans by dry weight, in a line that runs from 3,998 lbs to 10,334 lbs. It is the lightest plan in the line, which makes it the one to look at first if the tow vehicle is the constraint.

Plan the tow on loaded weight, not the 3,998 lbs dry figure: half the published cargo capacity brings this plan to about 4,834 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. 1600MRB-LE is a Alta designation and this site does not decode it into a layout claim.

How the 1600MRB-LE 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.

• Dry weight, 3,998 lb: lightest of seventeen; next is the 1800MBH-LE (4,284 lb).
• Tongue weight, 470 lb: lightest of seventeen; next is the 1800MBH-LE (495 lb).
• Length, 22 ft 10 in: shortest of seventeen; next is the 1800MBH-LE (24 ft).
• Exterior height, 10 ft 6 in: lowest of seventeen; next is the 1800MBH-LE (10 ft 7 in).
• Fresh tank, 46 gal: smallest of seventeen, level with the 1800MBH-LE; next is the 1900MMK (48 gal).
• Cargo capacity, 1,672 lb: sixth-smallest of seventeen, between the 2375KRK (1,477 lb) and the 2775KFK (1,817 lb).
• Grey tank, 30 gal: smallest of seventeen, level with the 1800MBH-LE, 1900MMK and 2410KML; next are the 2375KRK, 2400KTH and eight others (60 gal).
• Tongue weight as a share of dry weight, 11.8%: eighth-largest of seventeen, between the 1800MBH-LE and 3250KXT (11.6%) and the 3150KBH (12.6%).

Next to the 1800MBH-LE, the nearest heavier floorplan by dry weight, the 1600MRB-LE is 286 lb lighter by dry weight, has 361 lb more cargo capacity, has a tongue weight 25 lb lighter, is 1 ft 2 in shorter and stands 1 in lower; the two publish the same fresh tank, 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 46-gallon fresh tank is about 382 lb of water, 23% of the 1600MRB-LE’s 1,672 lb cargo capacity, leaving 1,290 lb. Across 17 Alta floorplans the water share runs 13% to 37%, and 7 give up more than this one. Nearest on that share: Alta 3010KBH at 22% and Alta 2650KRD at 24%.
