2027 Keystone Hampton372FDB

Keystone publishes three weights for the Hampton 372FDB: a shipping weight of 11,666 lb, a carrying capacity of 3,334 lb and a hitch weight of 1,974 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 Hampton 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 50 gal fresh, 78 gal gray and 78 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 415 lb on the road before anything else is loaded. The tire size Keystone lists is ST235/80R16G.

Against the 3 Hampton floorplans profiled here, this one is the 2nd by Keystone’s shipping weight, in a range from 11,515 lb (388FKL) to 12,072 lb (378DBB). 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 5 Nov 2026 from Keystone’s own floorplan page for the Hampton 372FDB. That page carries no model year, so the year comes from the roster page that links it, which lists the Hampton 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.

Keystone lists 3 Hampton floorplans for 2027. 3 have a complete Keystone figure set and no existing page here, and are profiled, from 11,515 lb to 12,072 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.
