2027 Keystone Fuzion440

Keystone publishes three weights for the Fuzion 440: a shipping weight of 17,490 lb, a carrying capacity of 3,510 lb and a hitch weight of 3,780 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 Fuzion 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 173 gal fresh, 104 gal gray and 104 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 1,436 lb on the road before anything else is loaded. The tire size Keystone lists is 215/75R17.5J; 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 5 Fuzion floorplans profiled here, this one is the 4th by Keystone’s shipping weight, in a range from 15,890 lb (373) to 17,540 lb (432). 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 5 Nov 2026 from Keystone’s own floorplan page for the Fuzion 440. That page carries no model year, so the year comes from the roster page that links it, which lists the Fuzion floorplans under the heading “2027 Floorplans” (this floorplan sits beyond the cards the page renders, and the heading’s own count equals the roster’s full list of floorplan pages). Keystone notes that its website reflects the most recent production run and that features and specifications change during the year.

How the 440 differs from the other four Fuzion floorplans. Most distinctive first. How these ranks are worked out.

• Hitch weight as a share of shipping weight, 21.6%: smallest of five; next is the 419 (22.1%).
• Shipping weight (Keystone’s term), 17,490 lb: second-heaviest of five, between the 419 (17,071 lb) and the 432 (17,540 lb).
• Carrying capacity (Keystone’s term), 3,510 lb: second-smallest of five, between the 432 (3,460 lb) and the 373 (3,855 lb).
• Hitch weight as Keystone lists it, 3,780 lb: third-lightest of five, between the 419 (3,770 lb) and the 442 (3,785 lb).
• Length, 45 ft 11 in: third-shortest of five, between the 419 (44 ft 6 in) and the 432 (46 ft).
• Sleeping capacity, 9: largest of five, level with the 442; next are the 373, 419 and 432 (8).

Next to the 419, the nearest lighter floorplan by shipping weight, the 440 is 419 lb heavier by shipping weight, has 419 lb less carrying capacity, has a hitch weight 10 lb heavier, is 1 ft 5 in longer and sleeps one more; the two publish the same exterior height, fresh tank and grey tank.

Next to the 432, the nearest heavier floorplan by shipping weight, the 440 is 50 lb lighter by shipping weight, has 50 lb more carrying capacity, has a hitch weight 280 lb lighter, is 1 in shorter and sleeps one more; the two publish the same exterior height, fresh tank and grey tank.

Keystone lists 6 Fuzion floorplans for 2027. 5 have a complete Keystone figure set and no existing page here, and are profiled, from 15,890 lb to 17,540 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.
