Highland Ridge lists the 2020 Mesa Ridge Conventional MR21FB at 4,275 lb dry, a GVWR of 6,000 lb, a net carrying capacity of 1,725 lb and a tongue weight of 545 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.

Among the 15 Mesa Ridge Conventional floorplans Highland Ridge’s Mesa Ridge Conventional brochure (filed under 2020 on its own site; the brochure prints no year) lists with a published dry weight, it is number 6 from the lightest, in a range from 3,445 lb (Mesa Ridge Conventional MR171RD) to 7,600 lb (Mesa Ridge Conventional MR32BHS). 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 Mesa Ridge Conventional brochure (filed under 2020 on its own site; the brochure prints no year); model year 2020 comes from where the maker files it on its own site, not from the document’s text.

• Cargo capacity, 1,725 lb: sixth-largest of fifteen, between the MR20FBS (1,720 lb) and the MR26BH (1,765 lb).
• Tongue weight as a share of dry weight, 12.7%: shared with the MR23RLS; of fifteen, twelve smaller and one larger, nearest the MR26BHS (12.6%) and the MR27RLI (14.4%).
• Tongue weight, 545 lb: seventh-lightest of fifteen, between the MR20MB (490 lb) and the MR21RBS (575 lb).
• GVWR, 6,000 lb: shared with the MR20FBS; of fifteen, five lower and eight higher, nearest the MR20MB (5,250 lb) and the MR23RLS and MR26BH (6,500 lb).
• Exterior height, 10 ft 6 in: shared with the MR20FBS and MR26BH; of fifteen, five lower and seven taller, nearest the MR19BH and MR20MB (10 ft 5 in) and the MR21RBS (10 ft 9 in).

Across 15 Mesa Ridge Conventional floorplans the water share runs 18% to 37%, and 6 give up more than this one. Nearest on that share: Mesa Ridge Conventional MR19BH at 23% and Mesa Ridge Conventional MR20FBS at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
