01 What makes it unique
Coachmen lists the 2026 Adrenaline 27 KB at 7,488 lb dry, a GVWR of 11,000 lb and a net carrying capacity of 3,512 lb. It prints no tongue weight for it. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 32'-11" long and 12' high. Coachmen prints its tanks as 98 gal fresh, 35 gal grey, 35 gal black.
Among the 6 Adrenaline floorplans Coachmen’s Adrenaline brochure (filed in Coachmen’s /brochures/2026/ folder; the brochure prints no year) lists with a published dry weight, it is number 4 from the lightest, in a range from 5,270 lb (Adrenaline 18 LT) to 9,033 lb (Adrenaline 30 GS). Every figure in that comparison is Coachmen’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from Coachmen’s Adrenaline brochure (filed in Coachmen’s /brochures/2026/ folder; the brochure prints no year); model year 2026 comes from where the maker files it on its own site, not from the document’s text.
How the KB differs from the other five Adrenaline floorplans. Most distinctive first. How these ranks are worked out.
- Cargo capacity, 3,512 lb: second-smallest of six, between the GS (3,466 lb) and the Adrenaline 21 LT (3,637 lb).
- Cargo capacity as a share of GVWR, 31.9%: second-smallest of four, between the SS (30.9%) and the Adrenaline 27 LT (35.3%).
- Dry weight, 7,488 lb: third-heaviest of six, between the Adrenaline 27 LT (6,790 lb) and the SS (8,642 lb).
- GVWR, 11,000 lb: third-highest of six, between the Adrenaline 27 LT (10,500 lb) and the GS and SS (12,500 lb).
- Exterior height, 12 ft: tallest of six, level with the GS and SS; next are the Adrenaline 18 LT, Adrenaline 21 LT and Adrenaline 27 LT (11 ft).
- Interior height, 7 ft 7 in: tallest of six, level with the GS and SS; next are the Adrenaline 18 LT, Adrenaline 21 LT and Adrenaline 27 LT (7 ft 1 in).
- Grey tank, 35 gal: smallest of six, level with the Adrenaline 18 LT and Adrenaline 27 LT; next is the SS (50 gal).
- Length, 32 ft: shared with the Adrenaline 27 LT; of six, two shorter and two longer, nearest the Adrenaline 21 LT (27 ft) and the SS (36 ft).
Next to the Adrenaline 27 LT, the nearest lighter floorplan by dry weight, the KB is 698 lb heavier by dry weight, has a GVWR 500 lb higher, has 198 lb less cargo capacity, stands 1 ft taller and has 6 in more interior height; the two publish the same length, fresh tank, grey tank and black tank.
Next to the SS, the nearest heavier floorplan by dry weight, the KB is 1,154 lb lighter by dry weight, has a GVWR 1,500 lb lower, has 346 lb less cargo capacity, is 4 ft shorter and has a grey tank 15 gal smaller; the two publish the same exterior height, interior height, fresh tank and black tank.

04 Notes on this floorplan
What Coachmen does not publish for the Adrenaline 27 KB
Coachmen prints no tongue weight, tire size, 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
6,790 lb dry and 10,500 lb GVWR, against this model’s 7,488 lb and 11,000 lb.
8,642 lb dry and 12,500 lb GVWR, against this model’s 7,488 lb and 11,000 lb.
06 Loading it for a trip
A full 98-gallon fresh tank is about 813 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 23% of the Adrenaline 27 KB’s 3,512 lb cargo capacity, leaving 2,699 lb. Across 6 Adrenaline floorplans the water share runs 20% to 23%, and 1 gives up more than this one. Nearest on that share: Adrenaline 21 LT at 22% and Adrenaline 30 GS at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
No source publishes a tongue weight for the Adrenaline 27 KB, so its hitch load has to come from a scale ticket taken with the trailer hitched.
07 Where this floorplan sits
Closest sibling: the Adrenaline 27 LT, nearest on the published figures. It differs on 3 of the 7 fields both publish (this plan first): dry weight 7,488 lb vs 6,790 lb; GVWR 11,000 lb vs 10,500 lb; cargo capacity 3,512 lb vs 3,710 lb. They match on length, fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 9 recall campaigns and 1 owner complaint (model years 2005 on) against the Coachmen Adrenaline line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 1 complaint has been filed on this line — not enough to say what fails most often. It covers electrical system.
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 Coachmen Adrenaline line page.
