01 What makes it unique
Keystone publishes three weights for the Coleman Legacy 2400REX: a shipping weight of 7,655 lb, a carrying capacity of 2,145 lb and a hitch weight of 1,345 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 Coleman 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, 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 448 lb on the road before anything else is loaded. The tire size Keystone lists is ST225/75R15D; 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 8 Coleman Legacy floorplans profiled here, this one is the 6th by Keystone’s shipping weight, in a range from 5,066 lb (1905RB) to 9,250 lb (2800SUNDECK). 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 Coleman Legacy 2400REX. That page carries no model year, so the year comes from the roster page that links it, which lists the Coleman Legacy 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 2400REX differs from the other two Coleman Legacy fifth wheels. 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), 7,655 lb: lightest of three; next is the 3000LOFT (8,840 lb).
- Carrying capacity (Keystone’s term), 2,145 lb: smallest of three; next is the 2800SUNDECK (2,350 lb).
- Hitch weight as Keystone lists it, 1,345 lb: lightest of three; next is the 2800SUNDECK (1,575 lb).
- Length, 28 ft 11 in: shortest of three; next is the 2800SUNDECK (32 ft 11 in).
- Hitch weight as a share of shipping weight, 17.6%: second-smallest of three, between the 2800SUNDECK (17%) and the 3000LOFT (18.9%).
- Sleeping capacity, 3: second-smallest of three, between the 2800SUNDECK (2) and the 3000LOFT (7).
Next to the 3000LOFT, the nearest heavier floorplan by shipping weight, the 2400REX is 1,185 lb lighter by shipping weight, has 515 lb less carrying capacity, has a hitch weight 325 lb lighter, is 6 ft shorter and sleeps four fewer; the two publish the same exterior height, fresh tank and grey tank.

04 Notes on this floorplan
What Keystone does not publish for the Coleman Legacy
No GVWR, no unloaded (dry) weight under that name, no dry hitch weight and no exterior width appear on Keystone’s floorplan pages for this series, so those rows read as not published. Nothing is filled from a sibling floorplan, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). On a Coleman those figures come from the trailer, not from this page, and they govern the towing decision.
05 How it compares
7,235 lb shipping weight against this plan’s 7,655 lb (Keystone’s figures, same series, same model year).
8,840 lb shipping weight and 2,660 lb carrying capacity, against this plan’s 7,655 lb and 2,145 lb.
07 Where this floorplan sits
Closest sibling: the Coleman Legacy 2800SUNDECK, nearest on the published figures. It differs on 3 of the 5 fields both publish (this plan first): length 28 ft 11 in vs 32 ft 11 in; sleeps 3 vs 2; hitch weight 1,345 lb vs 1,575 lb. They match on fresh tank and grey tank.

11 NHTSA safety record
NHTSA holds 11 recall campaigns and 2 owner complaints against the Coleman line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
Too few reports to show a pattern. 2 complaints have been filed on this line — not enough to say what fails most often. They cover structure.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Coleman line page.
