2026 Forest River Nightfall350N

The Nightfall 350N has 4,471 lbs of cargo capacity between 12,319 lbs dry and its 16,790 lbs GVWR, 27% of that rating; filling its 150-gallon fresh tank at 8.3 lb a gallon uses 1,245 lbs of it (how to read trailer weights).

Pin weight is 2,790 lbs, 23% of the dry weight as published; it rises as the trailer is loaded and comes off the truck’s payload, not its towing rating, so check it against the payload on your own door sticker (pin weight and payload).

Off hookups: 154 gallons of grey and black capacity against 150 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Nightfall fifth-wheel roster this is the 2nd of 5 fifth wheels by dry weight, in a line that runs from 9,459 lbs to 15,679 lbs. It sits in the middle of the line by weight.

Plan the tow on loaded weight, not the 12,319 lbs dry figure: half the published cargo capacity brings this plan to about 14,555 lbs, and the published GVWR of 16,790 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. A missing row means Forest River does not publish that figure (how figures are verified).

Forest River publishes no floorplan description for this plan in the channel this page is built from - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 350N is a Nightfall designation and this site does not decode it into a layout claim.

How the 350N differs from the other four Nightfall fifth wheels. Most distinctive first. How these ranks are worked out.

• Dry weight, 12,319 lb: second-lightest of five, between the 270N (9,459 lb) and the 343NHD (13,969 lb).
• GVWR, 16,790 lb: second-lowest of five, between the 270N (14,759 lb) and the 343NHD (17,250 lb).
• Cargo capacity, 4,471 lb: second-smallest of five, between the 343NHD (3,281 lb) and the 270N (5,300 lb).
• Cargo capacity as a share of GVWR, 26.6%: second-largest of five, between the 397NHD (25.4%) and the 270N (35.9%).
• Pin weight, 2,790 lb: second-lightest of five, between the 270N (2,165 lb) and the 404NHD (3,190 lb).
• Pin weight as a share of dry weight, 22.6%: second-smallest of five, between the 404NHD (20.3%) and the 270N (22.9%).
• Grey tank, 114 gal: second-smallest of five, between the 270N (97 gal) and the 343NHD, 397NHD and 404NHD (120 gal).
• Length, 40 ft 6 in: third-shortest of five, between the 343NHD (40 ft 5 in) and the 397NHD (45 ft).
• Exterior height, 13 ft 5 in: lowest of five, level with the 270N; next are the 343NHD, 397NHD and 404NHD (13 ft 6 in).
• Black tank, 40 gal: smallest of five, level with the 270N; next are the 343NHD, 397NHD and 404NHD (80 gal).

Next to the 270N, the nearest lighter floorplan by dry weight, the 350N is 2,860 lb heavier by dry weight, has a GVWR 2,031 lb higher, has 829 lb less cargo capacity, has a pin weight 625 lb heavier, is 8 ft 3 in longer and has a grey tank 17 gal larger; the two publish the same exterior height, fresh tank and black tank.

Next to the 343NHD, the nearest heavier floorplan by dry weight, the 350N is 1,650 lb lighter by dry weight, has a GVWR 460 lb lower, has 1,190 lb more cargo capacity, has a pin weight 460 lb lighter, is 1 in longer, stands 1 in lower, has a grey tank 6 gal smaller and has a black tank 40 gal smaller; the two publish the same fresh tank.

Nightfall is published as one roster that spans two different towing propositions, and the split is the first thing to understand about it. Forest River files fourteen floorplans under the name in three groupings - travel-trailer toy haulers, fifth-wheel toy haulers and HD fifth-wheel toy haulers - plus four more sold dealer-stock only. The bumper-pull plans run 6,758 to 9,383 lb dry with 1,175 to 1,500 lb on the tongue. The fifth wheels run 9,459 to 15,679 lb dry with 2,165 to 3,765 lb on the pin. Those are not two ends of one range; they are two trailer types sharing a badge, and the grouping a plan belongs to says more about its weight than its floorplan number does. Both are in the table below.

A full 150-gallon fresh tank is about 1,245 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 28% of the 350N’s 4,471 lb cargo capacity, leaving 3,226 lb. Across 5 Nightfall fifth-wheel floorplans the water share runs 23% to 38%, and 1 gives up more than this one. Nearest on that share: Nightfall 270N at 23% and Nightfall 343NHD at 38%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
