2027 Keystone Hideout Sport Single123BB

Keystone publishes three weights for the Hideout Sport Single 123BB: a shipping weight of 2,635 lb, a carrying capacity of 865 lb and a hitch weight of 375 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 Sport Single 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 5 Hideout Sport Single floorplans profiled here, this one is the 2nd by Keystone’s shipping weight, in a range from 2,630 lb (120BT) to 4,085 lb (199BHS). 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 Sport Single 123BB. That page carries no model year, so the year comes from the roster page that links it, which lists the Hideout Sport Single 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 123BB differs from the other four Hideout Sport Single floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Carrying capacity (Keystone’s term), 865 lb: smallest of five; next is the 120BT (870 lb).
• Shipping weight (Keystone’s term), 2,635 lb: second-lightest of five, between the 120BT (2,630 lb) and the 161BH (3,085 lb).
• Hitch weight as Keystone lists it, 375 lb: second-lightest of five, between the 161BH (340 lb) and the 120BT (400 lb).
• Hitch weight as a share of shipping weight, 14.2%: second-largest of five, between the 195RBS (12.9%) and the 120BT (15.2%).
• Sleeping capacity, 4: third-smallest of five, between the 195RBS (3) and the 161BH (5).
• Length, 15 ft 11 in: shortest of five, level with the 120BT; next is the 161BH (20 ft 6 in).

Next to the 120BT, the nearest lighter floorplan by shipping weight, the 123BB is 5 lb heavier by shipping weight, has 5 lb less carrying capacity, has a hitch weight 25 lb lighter and sleeps two more; the two publish the same length, exterior height, fresh tank and grey tank.

Next to the 161BH, the nearest heavier floorplan by shipping weight, the 123BB is 450 lb lighter by shipping weight, has 390 lb less carrying capacity, has a hitch weight 35 lb heavier, is 4 ft 7 in shorter, stands 1 in taller and sleeps one fewer; the two publish the same fresh tank and grey tank.

Keystone lists 6 Hideout Sport Single floorplans for 2027. 5 have a complete Keystone figure set and no existing page here, and are profiled, from 2,630 lb to 4,085 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 Sport Single 161BH, nearest on the published figures. It differs on 3 of the 5 fields both publish (this plan first): length 15 ft 11 in vs 20 ft 6 in; sleeps 4 vs 5; hitch weight 375 lb vs 340 lb. They match on fresh tank and grey tank.
