01 What makes it unique
Northwood lists the 2023 Fox Mountain 235RLS at 8,761 lb dry, a GVWR of 12,000 lb, a net carrying capacity of 3,239 lb and a pin weight of 1,930 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 27'10" long and 12'9" high. Northwood prints its tanks as 59 gal fresh, 42 gal grey, 36 gal black.
Among the 2 Fox Mountain floorplans Northwood’s Fox Mountain brochure (listed as the 2023 brochure in Northwood’s own brochure archive; the brochure prints no year) lists with a published dry weight, it is number 1 from the lightest, in a range from 8,761 lb (Fox Mountain 235RLS) to 9,215 lb (Fox Mountain 265RDS). Every figure in that comparison is Northwood’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from Northwood’s Fox Mountain brochure (listed as the 2023 brochure in Northwood’s own brochure archive; the brochure prints no year); model year 2023 comes from where the maker files it on its own site, not from the document’s text.
How the 235RLS differs from the other Fox Mountain floorplan. How these ranks are worked out.
Next to the 265RDS, the nearest heavier floorplan by dry weight, the 235RLS is 454 lb lighter by dry weight, has 454 lb more cargo capacity, has a pin weight 400 lb lighter, is 2 ft shorter, stands 1 in lower, has a fresh tank 5 gal larger, has a grey tank 2 gal larger and has a black tank 1 gal larger; the two publish the same GVWR.

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 ST235/80R16 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 (12,000 lb) and the upper loaded pin estimate (3,000 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 Fox Mountain floorplan family

04 Notes on this floorplan
What Northwood does not publish for the Fox Mountain 235RLS
Northwood prints no interior height, 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
9,215 lb dry and 12,000 lb GVWR, against this model’s 8,761 lb and 12,000 lb.
06 Loading it for a trip
A full 59-gallon fresh tank is about 490 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 15% of the Fox Mountain 235RLS’s 3,239 lb cargo capacity, leaving 2,749 lb. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

| Type | Date | Reference | What it says |
