Every figure in that comparison is Highland Ridge’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from Highland Ridge’s 2023 Mesa Ridge fifth-wheel brochure, the maker’s own dated document for model year 2023.

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 (15,500 lb) and the upper loaded pin estimate (3,875 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).

04 Notes on this floorplan
What Highland Ridge does not publish for the Mesa Ridge 379FBS
Highland Ridge prints no 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
12,240 lb dry and 15,000 lb GVWR, against this model’s 12,495 lb and 15,500 lb.
12,595 lb dry and 15,500 lb GVWR, against this model’s 12,495 lb and 15,500 lb.
06 Loading it for a trip

Across 7 Mesa Ridge floorplans the water share runs 23% to 30%, and this plan’s is the lowest. Nearest on that share: Mesa Ridge 395BHS at 24%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
