2027 Keystone Bullet Classic21RKC

Keystone publishes three weights for the Bullet Classic 21RKC: a shipping weight of 4,830 lb, a carrying capacity of 2,770 lb and a hitch weight of 550 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 Bullet Classic 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 45 gal fresh, 68 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 374 lb on the road before anything else is loaded. The tire size Keystone lists is ST215/75R14D.

Against the 8 Bullet Classic floorplans profiled here, this one is the 6th by Keystone’s shipping weight, in a range from 2,995 lb (16RBC) to 5,816 lb (28QBC). 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 19 Oct 2026 from Keystone’s own floorplan page for the Bullet Classic 21RKC. That page carries no model year, so the year comes from the roster page that links it, which lists the Bullet Classic 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 21RKC differs from the other seven Bullet Classic 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), 4,830 lb: third-heaviest of eight, between the 21BHC (4,130 lb) and the 26BHC (5,390 lb).
• Hitch weight as Keystone lists it, 550 lb: third-heaviest of eight, between the 21BHC (545 lb) and the 26BHC (610 lb).
• Length, 25 ft 5 in: third-longest of eight, between the 21BHC (25 ft 4 in) and the 26BHC (30 ft 4 in).
• Carrying capacity (Keystone’s term), 2,770 lb: fourth-largest of eight, between the 26BHC (2,210 lb) and the 21BHC (3,470 lb).
• Hitch weight as a share of shipping weight, 11.4%: fourth-smallest of eight, between the 26BHC (11.3%) and the 28QBC (12%).
• Grey tank, 68 gal: largest of eight, level with the 28QBC; next are the 16BHC, 16RBC and four others (34 gal).
• Sleeping capacity, 4: smallest of eight, level with the 16RBC, 18RBC and 19RDC; next are the 16BHC and 21BHC (6).
• Exterior height, 10 ft 9 in: shared with the 18RBC, 21BHC and 26BHC; of eight, three lower and one taller, nearest the 16BHC, 16RBC and 19RDC (10 ft 4 in) and the 28QBC (10 ft 10 in).

Next to the 21BHC, the nearest lighter floorplan by shipping weight, the 21RKC is 700 lb heavier by shipping weight, has 700 lb less carrying capacity, has a hitch weight 5 lb heavier, is 1 in longer, has a grey tank 34 gal larger and sleeps two fewer; the two publish the same exterior height and fresh tank.

Next to the 26BHC, the nearest heavier floorplan by shipping weight, the 21RKC is 560 lb lighter by shipping weight, has 560 lb more carrying capacity, has a hitch weight 60 lb lighter, is 4 ft 11 in shorter, has a grey tank 34 gal larger and sleeps four fewer; the two publish the same exterior height and fresh tank.

Keystone lists 13 Bullet Classic floorplans for 2027. 8 have a complete Keystone figure set and no existing page here, and are profiled, from 2,995 lb to 5,816 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 Bullet Classic 18RBC, nearest on the published figures. It differs on 3 of the 5 fields both publish (this plan first): length 25 ft 5 in vs 22 ft 4 in; hitch weight 550 lb vs 495 lb; grey tank 68 gal vs 34 gal. They match on sleeps and fresh tank.
