2027 Keystone Alpine Avalanche Edition380LT

Keystone publishes three weights for the Alpine Avalanche Edition 380LT: a shipping weight of 14,508 lb, a carrying capacity of 1,992 lb and a hitch weight of 2,605 lb. Those are Keystone’s own terms, and this page keeps them. Keystone does not call the first figure dry or unloaded weight, does not say the hitch figure is measured dry, and publishes no GVWR for any Alpine Avalanche Edition floorplan, so none of the three is renamed here and no loaded rating is worked out from them. The trailer’s own federal weight label, inside the door, is the document that carries its UVW, cargo capacity and GVWR.

Tank capacities are 75 gal fresh, 83 gal gray and 98 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 622 lb on the road before anything else is loaded. The tire size Keystone lists is ST235/80R16G; a fifth wheel puts its pin load into the truck bed, so it counts against the truck’s payload rather than its tow rating.

Against the 6 Alpine Avalanche Edition floorplans profiled here, this one is the 3rd by Keystone’s shipping weight, in a range from 12,200 lb (321RL) to 15,695 lb (381DL). Every figure in that comparison comes from the same Keystone page type for the same model year, so the comparison inside the series is like for like.

Every number on this page was read on 4 Nov 2026 from Keystone’s own floorplan page for the Alpine Avalanche Edition 380LT. That page carries no model year, so the year comes from the roster page that links it, which lists the Alpine Avalanche Edition floorplans under the heading “2027 Floorplans”. Keystone notes that its website reflects the most recent production run and that features and specifications change during the year.

How the 380LT differs from the other five Alpine Avalanche Edition floorplans. Most distinctive first. How these ranks are worked out.

• Carrying capacity (Keystone’s term), 1,992 lb: smallest of six; next are the 366LS and 390DS (2,300 lb).
• Hitch weight as a share of shipping weight, 18%: smallest of six; next is the 366LS (18.4%).
• Hitch weight as Keystone lists it, 2,605 lb: second-lightest of six, between the 321RL (2,420 lb) and the 366LS (2,625 lb).
• Shipping weight (Keystone’s term), 14,508 lb: third-lightest of six, between the 366LS (14,300 lb) and the 379MB (14,640 lb).
• Length, 42 ft 4 in: third-longest of six, between the 379MB (41 ft 11 in) and the 381DL and 390DS (42 ft 10 in).
• Sleeping capacity, 8: largest of six, level with the 379MB and 390DS; next are the 366LS and 381DL (6).

Next to the 366LS, the nearest lighter floorplan by shipping weight, the 380LT is 208 lb heavier by shipping weight, has 308 lb less carrying capacity, has a hitch weight 20 lb lighter, is 1 ft 6 in longer and sleeps two more; the two publish the same exterior height, fresh tank and grey tank.

Next to the 379MB, the nearest heavier floorplan by shipping weight, the 380LT is 132 lb lighter by shipping weight, has 348 lb less carrying capacity, has a hitch weight 375 lb lighter and is 5 in longer; the two publish the same exterior height, fresh tank, grey tank and sleeping capacity.

Keystone lists 7 Alpine Avalanche Edition floorplans for 2027. 6 have a complete Keystone figure set and no existing page here, and are profiled, from 12,200 lb to 15,695 lb shipping weight; the others are catalogued on this page with the reason against each. Keystone publishes shipping weight, carrying capacity and hitch weight for these trailers, and no GVWR.
