01 What makes it unique
Highland Ridge lists the 2027 Open Range 3X 390TBS at 14,795 lb dry, a GVWR of 16,995 lb, a net carrying capacity of 2,200 lb and a pin weight of 3,080 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 12' 2" high. Highland Ridge prints its tanks as 75 gal fresh, 97 gal grey, 80 gal black.
Every number on this page was read on 8 Nov 2026 from Highland Ridge’s own 2027 Open Range 3X floorplan page for the Open Range 3X 390TBS, whose heading names the model year 2027.
How the 390TBS differs from the other three Open Range 3X floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2027). How these ranks are worked out.
- Cargo capacity, 2,200 lb: smallest of four; next is the 287RLS (2,230 lb).
- Cargo capacity as a share of GVWR, 12.9%: smallest of four; next is the 393TBR (13.8%).
- Pin weight, 3,080 lb: heaviest of four; next is the 372MBH (2,990 lb).
- Dry weight, 14,795 lb: second-heaviest of four, between the 372MBH (13,950 lb) and the 393TBR (15,260 lb).
- GVWR, 16,995 lb: second-highest of four, between the 372MBH (16,300 lb) and the 393TBR (17,700 lb).
- Pin weight as a share of dry weight, 20.8%: second-largest of four, between the 287RLS (20.4%) and the 372MBH (21.4%).
- Exterior height, 12 ft 2 in: lowest of four, level with the 393TBR; next is the 372MBH (12 ft 5 in).
- Black tank, 80 gal: largest of four, level with the 393TBR; next are the 287RLS and 372MBH (40 gal).
- Sleeping capacity, 8: shared with the 372MBH; of four, one smaller and one larger, nearest the 287RLS (4) and the 393TBR (10).
Next to the 372MBH (2026 page), the nearest lighter floorplan by dry weight, the 390TBS is 845 lb heavier by dry weight, has a GVWR 695 lb higher, has 150 lb less cargo capacity, stands 3 in lower and has a black tank 40 gal larger; the two publish the same fresh tank, grey tank and sleeping capacity.
Next to the 393TBR (2026 page), the nearest heavier floorplan by dry weight, the 390TBS is 465 lb lighter by dry weight, has a GVWR 705 lb lower, has 240 lb less cargo capacity and sleeps two fewer; the two publish the same exterior height, fresh tank, grey tank and black tank.

How these published figures sit against the rest of the catalogue: fifth wheel pin weight and payload; fresh, grey and black tank sizes; camper trailer size chart.
Federal tire recalls naming this size. NHTSA’s recall file names ST235/85R16 in one tire recall: 21T018000 (Sailun Tire Americas, Inc., 2021; make SAILUN; models BLACKHAWK, BLACKLION, IRONHEAD, ROADX, SAILUN). A tire recall covers only the brands, lines and DOT date codes it lists, and this page does not know which brand of tire this trailer was built with, so read the brand and DOT code on your own sidewalls before relying on this list. Only 242 of NHTSA’s 788 tire recalls name a size in their summary, so a size with no match is not a clean record (NHTSA recall file, read 12 Oct 2026).

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 (16,995 lb) and the upper loaded pin estimate (4,249 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.
03 The Open Range 3X floorplan family
The Open Range 3X floorplan below was added from Highland Ridge’s 2027 Open Range 3X floorplan page; every Open Range 3X floorplan on this site, every model year, is listed on the Open Range 3X hub.

04 Notes on this floorplan
What Highland Ridge does not publish for the Open Range 3X 390TBS
Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
The weight label every RV trailer carries by law (49 CFR 571.110 and 571.120) governs the towing decision, not this page.
05 How it compares
06 Loading it for a trip
A full 75-gallon fresh tank is about 622 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 28% of the Open Range 3X 390TBS’s 2,200 lb cargo capacity, leaving 1,578 lb (197 lb per rated berth). Across 4 Open Range 3X floorplans the water share runs 26% to 28%, and this plan’s is the highest. Nearest on that share: Open Range 3X 287RLS at 28%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
