2027 Keystone Sprinter3920DSL

Keystone publishes three weights for the Sprinter 3920DSL: a shipping weight of 13,840 lb, a carrying capacity of 2,560 lb and a hitch weight of 2,685 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 Sprinter 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 77 gal fresh, 129 gal gray and 90 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 639 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 9 Sprinter floorplans profiled here, this one is the 8th by Keystone’s shipping weight, in a range from 11,441 lb (3520RDS) to 14,320 lb (3900DBL). 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 Sprinter 3920DSL. That page carries no model year, so the year comes from the roster page that links it, which lists the Sprinter 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 3920DSL differs from the other eight Sprinter floorplans. Most distinctive first. How these ranks are worked out.

• Hitch weight as Keystone lists it, 2,685 lb: second-heaviest of nine, between the 3910RLQ (2,670 lb) and the 3800FLB (2,745 lb).
• Carrying capacity (Keystone’s term), 2,560 lb: fourth-smallest of nine, between the 3520RDS (2,459 lb) and the 3910RLQ (2,625 lb).
• Hitch weight as a share of shipping weight, 19.4%: fourth-largest of nine, between the 3900DBL (18.5%) and the 3910RLQ (19.5%).
• Length, 42 ft 9 in: fourth-shortest of nine, between the 3640RLP (40 ft 5 in) and the 3840LRK (42 ft 10 in).

Keystone lists 12 Sprinter floorplans for 2027. 9 have a complete Keystone figure set and no existing page here, and are profiled, from 11,441 lb to 14,320 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.
