01 What makes it unique
Northwood lists the Arctic Fox NXT 325MK at 13,860 lb dry, a GVWR of 16,300 lb, a net carrying capacity of 2,440 lb and a pin weight of 3,120 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 88 gal fresh, 67 gal grey, 65 gal black.
Among the 12 Arctic Fox NXT floorplans Northwood’s Arctic Fox NXT 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 5,910 lb (Arctic Fox NXT 22GT) to 14,505 lb (Arctic Fox NXT 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 NXT model pages on northwoodmfg.com (no model year stated) for the Arctic Fox NXT 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 NXT fifth wheels. Most distinctive first. How these ranks are worked out.
- Pin weight, 3,120 lb: heaviest of five; next is the 365VS (2,840 lb).
- Pin weight as a share of dry weight, 22.5%: largest of five; next is the 295RK (22%).
- Dry weight, 13,860 lb: second-heaviest of five, between the 295RK (12,768 lb) and the 365VS (14,505 lb).
- Cargo capacity, 2,440 lb: second-smallest of five, between the 365VS (1,495 lb) and the 295RK (2,532 lb).
- Cargo capacity as a share of GVWR, 15%: second-smallest of four, between the 365VS (9.3%) and the 275LE (18.9%).
- 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 295RK, the nearest lighter floorplan by dry weight, the 325MK is 1,092 lb heavier by dry weight, has 92 lb less cargo capacity, has a pin weight 310 lb heavier, is 3 ft longer and stands 1 in lower; the two publish the same GVWR, fresh tank, black tank and sleeping capacity.
Next to the 365VS, the nearest heavier floorplan by dry weight, the 325MK is 645 lb lighter by dry weight, has a GVWR 300 lb higher, has 945 lb more cargo capacity, has a pin weight 280 lb heavier and is 2 ft 10 in shorter; the two publish the same exterior height, fresh tank, 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 NXT 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
12,768 lb dry and 16,300 lb GVWR, against this model’s 13,860 lb and 16,300 lb.
14,505 lb dry and 16,000 lb GVWR, against this model’s 13,860 lb and 16,300 lb.
06 Loading it for a trip
A full 88-gallon fresh tank is about 730 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 30% of the Arctic Fox NXT 325MK’s 2,440 lb cargo capacity, leaving 1,710 lb (427 lb per rated berth). Across 5 Arctic Fox NXT fifth-wheel floorplans the water share runs 24% to 49%, and 1 gives up more than this one. Nearest on that share: Arctic Fox NXT 295RK at 29% and Arctic Fox NXT 365VS at 49%. 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 NXT 295RK, nearest on the published figures.
