01 What makes it unique
Heartland lists the 2025 Corterra CT3.5 at 13,194 lb dry, a GVWR of 15,000 lb and a hitch weight of 3,136 lb. Heartland prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 39' 9-1/2" long and 13'6" high. Heartland prints no tank capacity for it.
Among the 3 Corterra floorplans Heartland’s 2025 Corterra brochure lists with a published dry weight, it is number 3 from the lightest, in a range from 10,430 lb (Corterra CT3.0) to 13,194 lb (Corterra CT3.5). Every figure in that comparison is Heartland’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from Heartland’s 2025 Corterra brochure, the maker’s own dated document for model year 2025.

04 Notes on this floorplan
What Heartland does not publish for the Corterra CT3.5
Heartland prints no cargo carrying capacity, tire size, interior height, grey-tank, black-tank, sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, 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). Those figures come from the trailer itself and govern the towing decision.
05 How it compares
12,618 lb dry and 15,000 lb GVWR, against this model’s 13,194 lb and 15,000 lb.
06 Loading it for a trip
No source publishes a tongue weight for the Corterra CT3.5, so its hitch load has to come from a scale ticket taken with the trailer hitched.
07 Where this floorplan sits
Closest sibling: the Corterra CT3.7, nearest on the published figures. It differs on 2 of the 3 fields both publish (this plan first): length 39 ft 9 in vs 41 ft 9 in; dry weight 13,194 lb vs 12,618 lb. They match on GVWR.
