01 What XLR Nitro is
XLR Nitro is the heaviest line in this group and it is a one-truck-class proposition throughout: five published floorplans from 13,124 to 16,949 lb dry, on dry pin weights of 3,160 to 3,765 lb. A pin weight in that band consumes most of a one-ton pickup's payload before anyone loads the garage, and cargo capacity runs 3,281 to 5,326 lb on top of it. Forest River publishes no GVWR for any Nitro floorplan, so the rating a buyer needs to check against is not in the factory's own spec channel.
Across the whole XLR Nitro roster the published dry weights run from 13,124 lbs to 16,949 lbs, cargo capacities from 3,281 lbs to 5,326 lbs, and dry pin weights from 3,160 lbs to 3,765 lbs. Exterior lengths run 38 to 45 feet. Those are Forest River's figures for a standard build, captured from the factory roster block and confirmed against each floorplan's own factory page.
There is one thing to know before comparing XLR Nitro against anything else: Forest River publishes no GVWR for this line. Dry weight, cargo capacity and dry pin weight are published for every floorplan; the loaded rating is not. The factory's own glossary defines cargo capacity as GVWR minus unloaded weight, so the rating can be worked out - and a figure worked out is not a figure the manufacturer published, so this site does not print one as though it were. The weight label on the trailer itself carries the real number.
02 Floorplans profiled in depth
5 of the 5 XLR Nitro floorplans are profiled in full below, each on its own page with the complete factory weight, dimension and tank block. The profiled set is spread across the weight range rather than taken from one end of it, so the lightest and heaviest plans in the line are both represented. Every plan profiled here publishes a full field set and, where Forest River publishes a GVWR, passes the dry-plus-cargo arithmetic check.
| Floorplan | Dry wt | Length | Cargo | Pin wt | Factory grouping |
|---|---|---|---|---|---|
| 32W17 | 13,124 | 38' 4" | 4,036 | 3,160 | XLR Nitro Fifth Wheels |
| 35G13 | 13,969 | 40' 5" | 3,281 | 3,250 | XLR Nitro Fifth Wheels |
| 40G17 | 15,674 | 45' 0" | 5,326 | 3,765 | XLR Nitro Fifth Wheels |
| 41G14 | 15,679 | 45' 1" | 5,321 | 3,190 | XLR Nitro Fifth Wheels |
| 40BAR13 | 16,949 | 45' 6" | 4,051 | 3,480 | XLR Nitro Fifth Wheels |
Every figure in this table is a Forest River factory publication for 2026, captured twice - from the line roster block and from each floorplan's own factory page - and cross-checked field by field. Forest River publishes no sleeping capacity, axle count, tire size or MSRP for this line, so there are no columns for them.
03 Also in the 2026 line
The remaining 0 XLR Nitro floorplans are catalogued here from the factory's published figures. A plan is catalogued rather than profiled when the factory has not yet published its full field set, when its own published figures disagree with each other, or simply because the profiled set is capped. Nothing in this table is estimated.
| Floorplan | Dry wt | GVWR | Cargo | Pin wt | Status |
|---|
Catalogued plans carry the factory figures Forest River publishes and nothing else. A row reading “Not published” means the factory does not publish that field for that plan - it is never a placeholder for a figure this site could not be bothered to find.
04 How to choose
Sort this line by the constraint you actually have. If the truck is fixed, start at the weight column: the lightest plan in the roster is the 32W17 at 13,124 lbs dry and the heaviest is the 40BAR13 at 16,949 lbs, and that spread is wide enough that the two ends are not the same buying decision. If the truck is not fixed, sort by cargo capacity instead - the 40G17 carries the most at 5,326 lbs, and payload is the number that runs out first on a long trip.
Do not sort by floorplan number. Forest River's codes encode length loosely and layout not at all, and this site does not decode them into layout claims. Two plans with adjacent numbers in this roster can differ by hundreds of pounds of dry weight and by more than that in dry pin weight, which is the figure that determines what the truck has to be.
Where Forest River publishes a floorplan description it is quoted on the plan page and identified as factory marketing copy rather than a specification. Where it publishes none, the plan page says so instead of describing a layout that nobody has verified. That is the difference between a catalogue and a brochure.
05 What to weigh before buying
What this line is
XLR Nitro is Forest River's full-size fifth-wheel toy hauler, five floorplans published, from 38 feet 4 inches to 45 feet 6 inches. Forest River publishes dry weight, cargo capacity, dry pin weight, all three exterior dimensions and all three tank capacities for every plan, awning size for four of five, and no GVWR for any of them - so that row reads as unpublished rather than computed from cargo capacity. Sleeping capacity, axle count, tire size and MSRP are not published in this channel. Garage length is not published either, which for a toy hauler is the field a buyer most wants and the one this source does not carry.
Five fields Forest River does not publish, and GVWR is one of them
Sleeping capacity, axle count, tire size, MSRP and GVWR are all absent from Forest River's specification channel for XLR Nitro. The GVWR absence is the unusual one and it is not an omission on this page: the factory spec block runs pin weight, unloaded weight, cargo capacity, dimensions and tanks, and stops. Any GVWR you see quoted for a XLR Nitro came from somewhere other than Forest River's own channel.
Match the truck honestly
The plans here run from 13,124 lbs to 16,949 lbs dry with dry pin weights of 3,160 lbs to 3,765 lbs. Dry weight is not towing weight - water, batteries, propane, gear and dealer-installed accessories all sit on top of it, and pin weight rises with them. For a fifth wheel the pin load comes off the truck's payload rating rather than its towing rating, which is the number most often quoted and the wrong one. Read your own door sticker, and weigh the trailer loaded the way you actually travel.
