01 What makes it unique
Coachmen lists the 2023 Clipper 4K 18BH at 3,420 lb dry, a GVWR of 4,125 lb, a net carrying capacity of 705 lb and a tongue weight of 400 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 20' 5" 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 8 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.
How the 18BH differs from the other twelve Clipper floorplans. Most distinctive first. How these ranks are worked out.
- GVWR, 4,125 lb: fifth-highest of thirteen, between the 18FQ (4,090 lb) and the 182DBU (4,433 lb).
- Cargo capacity, 705 lb: fifth-smallest of thirteen, between the 18FQ (700 lb) and the 18BHS (735 lb).
- Tongue weight as a share of dry weight, 11.7%: fifth-largest of thirteen, between the 262BHS (11.6%) and the 18FQ (11.8%).
- Dry weight, 3,420 lb: sixth-heaviest of thirteen, between the 18FQ (3,390 lb) and the 17MBS (3,550 lb).
- Cargo capacity as a share of GVWR, 17.1%: shared with the 18FQ; of twelve, four smaller and six larger, nearest the 162RBU and 18BHS (16.2%) and the 17CFQ (24.4%).
- Tongue weight, 400 lb: shared with the 17MBS and 18FQ; of thirteen, six lighter and four heavier, nearest the 162RBU (360 lb) and the 182DBU and 18BHS (425 lb).
- Length, 20 ft 5 in: shared with the 17CBH, 17CFQ and two others; of thirteen, four shorter and four longer, nearest the 162RBU (19 ft 9 in) and the 18BHS (21 ft 6 in).
Next to the 18FQ, the nearest lighter floorplan by dry weight, the 18BH is 30 lb heavier by dry weight, has a GVWR 35 lb higher and has 5 lb more cargo capacity; the two publish the same tongue weight, length, exterior height, interior height, fresh tank, grey tank and black tank.
Next to the 17MBS, the nearest heavier floorplan by dry weight, the 18BH is 130 lb lighter by dry weight, has a GVWR 82 lb higher and has 212 lb more cargo capacity; the two publish the same tongue weight, length, exterior height, interior height, fresh tank, grey tank and black tank.

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 (4,125 lb) and the upper loaded tongue estimate (619 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 18BH
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
3,390 lb dry and 4,090 lb GVWR, against this model’s 3,420 lb and 4,125 lb.
3,550 lb dry and 4,043 lb GVWR, against this model’s 3,420 lb and 4,125 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), 47% of the Clipper 4K 18BH’s 705 lb cargo capacity, leaving 373 lb. Across 13 Clipper floorplans the water share runs 16% to 67%, and 4 give up more than this one. Nearest on that share: Clipper 4K 18BHS at 45% and Clipper 4K 18FQ 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 18FQ, nearest on the published figures.

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.
