2027 Keystone Hideout Max310XBR

Keystone publishes three weights for the Hideout Max 310XBR: a shipping weight of 8,325 lb, a carrying capacity of 2,830 lb and a hitch weight of 955 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 Hideout Max 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 54 gal fresh, 39 gal gray and 39 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 448 lb on the road before anything else is loaded. The tire size Keystone lists is ST225/75R15D.

Against the 3 Hideout Max floorplans profiled here, this one is the 3rd by Keystone’s shipping weight, in a range from 7,340 lb (29HAVEN) to 8,325 lb (310XBR). 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 Hideout Max 310XBR. That page carries no model year, so the year comes from the roster page that links it, which lists the Hideout Max 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 310XBR differs from the other two Hideout Max floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Shipping weight (Keystone’s term), 8,325 lb: heaviest of three; next is the 31SUNROOM (7,530 lb).
• Carrying capacity (Keystone’s term), 2,830 lb: largest of three; next is the 29HAVEN (2,160 lb).
• Sleeping capacity, 8: largest of three; next is the 31SUNROOM (4).
• Hitch weight as Keystone lists it, 955 lb: second-lightest of three, between the 31SUNROOM (815 lb) and the 29HAVEN (1,055 lb).
• Hitch weight as a share of shipping weight, 11.5%: second-smallest of three, between the 31SUNROOM (10.8%) and the 29HAVEN (14.4%).

Next to the 31SUNROOM, the nearest lighter floorplan by shipping weight, the 310XBR is 795 lb heavier by shipping weight, has 860 lb more carrying capacity, has a hitch weight 140 lb heavier, stands 2 in taller and sleeps four more; the two publish the same length, fresh tank and grey tank.

Keystone lists 3 Hideout Max floorplans for 2027. 3 have a complete Keystone figure set and no existing page here, and are profiled, from 7,340 lb to 8,325 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 Hideout Max 31SUNROOM, nearest on the published figures. It differs on 2 of the 5 fields both publish (this plan first): sleeps 8 vs 4; hitch weight 955 lb vs 815 lb. They match on length, fresh tank and grey tank.
