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 (11,260 lb) and the upper loaded tongue estimate (1,689 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, 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 Forest River does not publish for the Nightfall 21N
Forest River prints no tire size, 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
6,793 lb dry and 11,370 lb GVWR, against this model’s 7,013 lb and 11,260 lb.
7,163 lb dry and 11,455 lb GVWR, against this model’s 7,013 lb and 11,260 lb.
06 Loading it for a trip
A full 87-gallon fresh tank is about 722 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 17% of the Nightfall 21N’s 4,247 lb cargo capacity, leaving 3,525 lb. Across 8 Nightfall travel-trailer floorplans the water share runs 17% to 21%, and 6 give up more than this one. Nearest on that share: Nightfall 28N at 17% and Nightfall 20N at 17%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
