01 What makes it unique
Jayco lists the 2017 Designer 39RE at 15,115 lb dry, a GVWR of 17,995 lb, a net carrying capacity of 2,880 lb and a pin weight of 2,796 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 42' 5" long and 159" high. Jayco prints its tanks as 85 gal fresh, 95 gal grey, 50 gal black.
Among the 4 Designer floorplans Jayco’s 2017 Designer brochure lists with a published dry weight, it is number 4 from the lightest, in a range from 14,370 lb (Designer 37RS) to 15,115 lb (Designer 39RE). Every figure in that comparison is Jayco’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from Jayco’s 2017 Designer brochure, the maker’s own dated document for model year 2017.
How the 39RE differs from the other three Designer floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 15,115 lb: heaviest of four; next is the 39FL (14,815 lb).
- Cargo capacity, 2,880 lb: smallest of four; next is the 37FB (2,915 lb).
- Cargo capacity as a share of GVWR, 16%: smallest of four; next is the 37FB (16.7%).

- Pin weight as a share of dry weight, 18.5%: smallest of four; next is the 37FB (19.2%).
- Length, 42 ft 5 in: longest of four; next is the 39FL (41 ft 6 in).
- GVWR, 17,995 lb: highest of four, level with the 39FL; next are the 37FB and 37RS (17,500 lb).

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (17,995 lb) and the upper loaded pin estimate (4,499 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.

04 Notes on this floorplan
What Jayco does not publish for the Designer 39RE
Jayco prints no tire size 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
14,815 lb dry and 17,995 lb GVWR, against this model’s 15,115 lb and 17,995 lb.
06 Loading it for a trip
A full 85-gallon fresh tank is about 706 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 24% of the Designer 39RE’s 2,880 lb cargo capacity, leaving 2,174 lb (362 lb per rated berth). Across 4 Designer floorplans the water share runs 22% to 24%, and this plan’s is the highest. Nearest on that share: Designer 37FB at 24%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
Closest sibling: the Designer 37FB, nearest on the published figures. It differs on 6 of the 9 fields both publish (this plan first): length 42 ft 5 in vs 41 ft 1 in; sleeps 6 vs 4; dry weight 15,115 lb vs 14,585 lb; GVWR 17,995 lb vs 17,500 lb; cargo capacity 2,880 lb vs 2,915 lb; hitch weight 2,796 lb vs 2,805 lb. They match on fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 11 recall campaigns and 4 owner complaints (model years 2005 on) against the Designer line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 4 complaints have been filed on this line — not enough to say what fails most often. They cover electrical system and tires.
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 Designer line page.
