01 What makes it unique
Coachmen lists the 2023 Clipper 4K 18BHS at 3,790 lb dry, a GVWR of 4,525 lb, a net carrying capacity of 735 lb and a tongue weight of 425 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 21' 6" long and 10' high. Coachmen prints its tanks as 40 gal fresh, 32 gal grey, 32 gal black.
Among the 13 Clipper floorplans Coachmen’s 2023 Clipper brochure lists with a published dry weight, it is number 10 from the lightest, in a range from 2,450 lb (Clipper 3K 14CR) to 6,226 lb (Clipper 6K 262BHS). Every figure in that comparison is Coachmen’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from Coachmen’s 2023 Clipper brochure, the maker’s own dated document for model year 2023.

- Tongue weight as a share of dry weight, 11.2%: fifth-smallest of thirteen, between the 162RBU and 182DBU (11.1%) and the 17CFQ and 17MBS (11.3%).
- Cargo capacity, 735 lb: sixth-smallest of thirteen, between the 18BH (705 lb) and the 17CFQ (940 lb).
- Cargo capacity as a share of GVWR, 16.2%: shared with the 162RBU; of twelve, two smaller and eight larger, nearest the 182DBU (13.4%) and the 18BH and 18FQ (17.1%).

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 (4,525 lb) and the upper loaded tongue estimate (679 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433).

04 Notes on this floorplan
What Coachmen does not publish for the Clipper 4K 18BHS
Coachmen prints no 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
3,550 lb dry and 4,043 lb GVWR, against this model’s 3,790 lb and 4,525 lb.
3,840 lb dry and 4,433 lb GVWR, against this model’s 3,790 lb and 4,525 lb.
06 Loading it for a trip
A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 45% of the Clipper 4K 18BHS’s 735 lb cargo capacity, leaving 403 lb. Across 13 Clipper floorplans the water share runs 16% to 67%, and 5 give up more than this one. Nearest on that share: Clipper 3K 17CFQ at 24% and Clipper 4K 18BH at 47%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
07 Where this floorplan sits
Closest sibling: the Clipper 4K 182DBU, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): length 21 ft 6 in vs 22 ft 3 in; dry weight 3,790 lb vs 3,840 lb; GVWR 4,525 lb vs 4,433 lb; cargo capacity 735 lb vs 593 lb. They match on hitch weight, fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 12 recall campaigns and 9 owner complaints (model years 2005 on) against the Clipper line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 9 complaints have been filed on this line — not enough to say what fails most often. They cover unknown or other, structure, service brakes, suspension and trailer hitches.
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 Clipper line page.
