01 What makes it unique
Northwood lists the Arctic Fox Edge 325MK at 13,965 lb dry, a GVWR of 16,300 lb, a net carrying capacity of 2,335 lb and a pin weight of 3,110 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 36’10” long and 13’5″ high. Northwood prints its tanks as 82 gal fresh, 67 gal grey, 65 gal black.
Among the 12 Arctic Fox Edge floorplans Northwood’s Arctic Fox Edge model pages on northwoodmfg.com (no model year stated) lists with a published dry weight, it is number 11 from the lightest, in a range from 6,545 lb (Arctic Fox Edge 22GT) to 14,825 lb (Arctic Fox Edge 365VS). Every figure in that comparison is Northwood’s, read from the same set of model pages.
Every number on this page was read on 6 Nov 2026 from Northwood’s own Arctic Fox Edge model pages on northwoodmfg.com (no model year stated) for the Arctic Fox Edge 325MK, which names no model year; the figures are shown as the maker published them, and no year is claimed for them.
How the 325MK differs from the other four Arctic Fox Edge fifth wheels. Most distinctive first. How these ranks are worked out.
- Pin weight, 3,110 lb: heaviest of five; next is the 365VS (3,040 lb).
- Fresh tank, 82 gal: smallest of five; next are the 275LE, 295RK and two others (88 gal).
- Dry weight, 13,965 lb: second-heaviest of five, between the 295RL (12,870 lb) and the 365VS (14,825 lb).
- Cargo capacity, 2,335 lb: second-smallest of five, between the 365VS (1,175 lb) and the 275LE (2,690 lb).
- Cargo capacity as a share of GVWR, 14.3%: second-smallest of five, between the 365VS (7.3%) and the 295RL (18.5%).
- Pin weight as a share of dry weight, 22.3%: second-largest of five, between the 275LE (21.4%) and the 295RK (22.6%).
- Length, 36 ft 10 in: second-longest of five, between the 295RL (34 ft 7 in) and the 365VS (39 ft 8 in).
- GVWR, 16,300 lb: highest of five, level with the 295RK; next is the 365VS (16,000 lb).
Next to the 295RL, the nearest lighter floorplan by dry weight, the 325MK is 1,095 lb heavier by dry weight, has a GVWR 500 lb higher, has 595 lb less cargo capacity, has a pin weight 470 lb heavier, is 2 ft 3 in longer, stands 1 in taller and has a fresh tank 6 gal smaller; the two publish the same grey tank, black tank and sleeping capacity.
Next to the 365VS, the nearest heavier floorplan by dry weight, the 325MK is 860 lb lighter by dry weight, has a GVWR 300 lb higher, has 1,160 lb more cargo capacity, has a pin weight 70 lb heavier, is 2 ft 10 in shorter and has a fresh tank 6 gal smaller; the two publish the same exterior height, grey tank, black tank and sleeping capacity.

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 (16,300 lb) and the upper loaded pin estimate (4,075 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.

04 Notes on this floorplan
What Northwood does not publish for the Arctic Fox Edge 325MK
Northwood prints no interior height 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
12,870 lb dry and 15,800 lb GVWR, against this model’s 13,965 lb and 16,300 lb.
14,825 lb dry and 16,000 lb GVWR, against this model’s 13,965 lb and 16,300 lb.
06 Loading it for a trip
A full 82-gallon fresh tank is about 681 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 29% of the Arctic Fox Edge 325MK’s 2,335 lb cargo capacity, leaving 1,654 lb (414 lb per rated berth). Across 5 Arctic Fox Edge fifth-wheel floorplans the water share runs 20% to 62%, and 1 gives up more than this one. Nearest on that share: Arctic Fox Edge 275LE at 27% and Arctic Fox Edge 365VS at 62%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
Closest sibling: the Arctic Fox Edge 295RL, nearest on the published figures. It differs on 6 of the 9 fields both publish (this plan first): length 36 ft 10 in vs 34 ft 7 in; dry weight 13,965 lb vs 12,870 lb; GVWR 16,300 lb vs 15,800 lb; cargo capacity 2,335 lb vs 2,930 lb; hitch weight 3,110 lb vs 2,640 lb; fresh tank 82 gal vs 88 gal.
