2026 Forest River Nightfall343NHD

The Nightfall 343NHD has 3,281 lbs of cargo capacity between 13,969 lbs dry and its 17,250 lbs GVWR, 19% 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 3,250 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: 200 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 3rd 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 13,969 lbs dry figure: half the published cargo capacity brings this plan to about 15,609 lbs, and the published GVWR of 17,250 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. 343NHD is a Nightfall designation and this site does not decode it into a layout claim.

How the 343NHD differs from the other four Nightfall fifth wheels. Most distinctive first. How these ranks are worked out.

• Cargo capacity, 3,281 lb: smallest of five; next is the 350N (4,471 lb).
• Cargo capacity as a share of GVWR, 19%: smallest of five; next is the 404NHD (25.3%).
• Pin weight, 3,250 lb: second-heaviest of five, between the 404NHD (3,190 lb) and the 397NHD (3,765 lb).
• Pin weight as a share of dry weight, 23.3%: second-largest of five, between the 270N (22.9%) and the 397NHD (24%).
• Length, 40 ft 5 in: second-shortest of five, between the 270N (32 ft 3 in) and the 350N (40 ft 6 in).
• Dry weight, 13,969 lb: third-lightest of five, between the 350N (12,319 lb) and the 397NHD (15,674 lb).
• GVWR, 17,250 lb: third-lowest of five, between the 350N (16,790 lb) and the 397NHD and 404NHD (21,000 lb).

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

Next to the 397NHD, the nearest heavier floorplan by dry weight, the 343NHD is 1,705 lb lighter by dry weight, has a GVWR 3,750 lb lower, has 2,045 lb less cargo capacity, has a pin weight 515 lb lighter and is 4 ft 7 in shorter; the two publish the same exterior height, fresh tank, grey tank and black 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), 38% of the 343NHD’s 3,281 lb cargo capacity, leaving 2,036 lb. Across 5 Nightfall fifth-wheel floorplans the water share runs 23% to 38%, and this plan’s is the highest. Nearest on that share: Nightfall 350N at 28%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
