2026 Forest River Nightfall404NHD

The Nightfall 404NHD has 5,321 lbs of cargo capacity between 15,679 lbs dry and its 21,000 lbs GVWR, 25% 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 3,190 lbs, 20% 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 5th of 5 fifth wheels by dry weight, in a line that runs from 9,459 lbs to 15,679 lbs. It is the heaviest fifth wheel in the line, so the tow vehicle should be settled before the floorplan is.

Plan the tow on loaded weight, not the 15,679 lbs dry figure: half the published cargo capacity brings this plan to about 18,339 lbs, and the published GVWR of 21,000 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. 404NHD is a Nightfall designation and this site does not decode it into a layout claim.

How the 404NHD differs from the other four Nightfall fifth wheels. Most distinctive first. How these ranks are worked out.

• Dry weight, 15,679 lb: heaviest of five; next is the 397NHD (15,674 lb).
• Pin weight as a share of dry weight, 20.3%: smallest of five; next is the 350N (22.6%).
• Length, 45 ft 1 in: longest of five; next is the 397NHD (45 ft).
• Cargo capacity, 5,321 lb: second-largest of five, between the 270N (5,300 lb) and the 397NHD (5,326 lb).
• Cargo capacity as a share of GVWR, 25.3%: second-smallest of five, between the 343NHD (19%) and the 397NHD (25.4%).
• Pin weight, 3,190 lb: third-lightest of five, between the 350N (2,790 lb) and the 343NHD (3,250 lb).
• GVWR, 21,000 lb: highest of five, level with the 397NHD; next is the 343NHD (17,250 lb).

Next to the 397NHD, the nearest lighter floorplan by dry weight, the 404NHD is 5 lb heavier by dry weight, has 5 lb less cargo capacity, has a pin weight 575 lb lighter and is 1 in longer; the two publish the same GVWR, 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), 23% of the 404NHD’s 5,321 lb cargo capacity, leaving 4,076 lb. Across 5 Nightfall fifth-wheel floorplans the water share runs 23% to 38%, and 3 give up more than this one. Nearest on that share: Nightfall 397NHD at 23% and Nightfall 270N at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
