2027 Keystone Springdale Mini1660RB

Keystone publishes three weights for the Springdale Mini 1660RB: a shipping weight of 3,119 lb, a carrying capacity of 1,236 lb and a hitch weight of 355 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 Springdale Mini 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 21 gal fresh, 34 gal gray and 34 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 174 lb on the road before anything else is loaded. The tire size Keystone lists is ST205/75R14D.

Against the 6 Springdale Mini floorplans profiled here, this one is the 3rd by Keystone’s shipping weight, in a range from 2,578 lb (1230BB) to 4,029 lb (1990BHS). 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 23 Oct 2026 from Keystone’s own floorplan page for the Springdale Mini 1660RB. That page carries no model year, so the year comes from the roster page that links it, which lists the Springdale Mini 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 1660RB differs from the other five Springdale Mini floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Exterior height, 9 ft 11 in: second-lowest of six, between the 1610BH (9 ft 10 in) and the 1200BT, 1230BB and two others (10 ft).

Next to the 1610BH, the nearest heavier floorplan by shipping weight, the 1660RB is 9 lb lighter by shipping weight, has 9 lb more carrying capacity, stands 1 in taller and sleeps two fewer; the two publish the same hitch weight, length, fresh tank and grey tank.

Keystone lists 6 Springdale Mini floorplans for 2027. 6 have a complete Keystone figure set and no existing page here, and are profiled, from 2,578 lb to 4,029 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.

Closest sibling: the Springdale Mini 1610BH, nearest on the published figures. It differs on 1 of the 5 fields both publish (this plan first): sleeps 3 vs 5. They match on length, hitch weight, fresh tank and grey tank.
