2026 Forest River Vengeance Rogue391T145

The Vengeance Rogue 391T145 leaves Forest River's factory at 14,014 lbs dry, with a published GVWR of 17,385 lbs and 3,371 lbs of cargo capacity between the two. Cargo capacity is 19% of the loaded rating, and Forest River's own definition is worth reading before you plan against it: cargo capacity is what remains for fresh water, gear, food, batteries and every dealer-installed accessory. Fresh water alone is 8.3 lb per gallon, so filling this trailer's 160-gallon fresh tank spends 1,328 lbs of that 3,371 lbs before anything else is loaded.

Dry pin weight is 3,385 lbs, which is 24% of the dry weight. That figure lands on the truck's rear axle and comes straight off its payload rating - not its towing rating, which is the number most often quoted and the wrong one for this decision. Pin weight rises as the trailer is loaded, and a fifth wheel loaded toward its cargo capacity will put substantially more than 3,385 lbs over the bed. Read the payload figure on your own door sticker rather than a brochure maximum for the model.

Tank capacities are 160 gallons fresh, 100 grey and 80 black, 180 gallons of waste capacity against 160 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Forest River publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.

Against the rest of the Vengeance Rogue roster this is the 14th of 14 floorplans by dry weight, in a line that runs from 5,498 lbs to 14,014 lbs. It is the heaviest plan in the line, so the tow vehicle should be settled before the floorplan is. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.

A useful way to read the pair of weights is to stop planning against the dry figure. Nobody tows a trailer at 14,014 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity, which is modest for a family trip, and this plan is already near 15,700 lbs on the road. Compare that number against the tow vehicle, not the dry weight, and leave margin on top of it - the published GVWR of 17,385 lbs is a limit rather than a target.

Every number above was captured twice from Forest River and checked against itself before it was published. The line roster block and the individual floorplan page are two separate factory renderings of the same trailer, and this plan's 4 shared figures agree exactly on both. Dry weight plus cargo capacity also equals the published GVWR exactly, which is the arithmetic check this site runs on every profiled floorplan. Where a figure is missing from this page it is because Forest River does not publish it in this channel, not because it was hard to find - and the row says so rather than being quietly dropped.

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. 391T145 is a Vengeance Rogue designation and this site does not decode it into a layout claim.

Vengeance Rogue is published as three rosters that span two different towing propositions, and the split is the first thing to understand about the line. The SUT and Armored Travel Trailer plans are bumper-pull toy haulers running 5,498 to 10,219 lb dry with tongue weights of 1,036 to 1,620 lb. The Armored fifth wheels start where those stop: 12,874 to 14,014 lb dry on pin weights of 2,990 to 3,385 lb, which is three-quarter-ton and one-ton territory with a properly rated in-bed hitch. Nothing on this hub mixes the two -- every floorplan page names its own hitch class and no pin figure appears in a tongue row. Forest River publishes a GVWR for all fourteen, and dry plus cargo equals it exactly on every one.

Fresh water is the single biggest line in this floorplan’s load plan. A full 160-gallon tank is about 40% of the 3,371-pound cargo capacity — enough that whether you tow with water aboard is a real decision on the 391T145 rather than a detail.

The published dry pin weight of 3,385 pounds is 24% of this floorplan’s 14,014-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Nothing above changes the ceiling. Loaded to its 17,385-pound GVWR the 391T145 is towing 3,371 pounds more than its 14,014-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 160 gallons of fresh against 100 grey and 80 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Of the 12 Vengeance Rogue floorplans profiled here, the 391T145 carries the highest GVWR at 17,385 pounds. It is the top of the line by weight, which makes tow-vehicle capability the first thing to settle rather than the last.

Either side of it in the same line: Vengeance Rogue 351G2 is 335 pounds lighter at 17,050 lb GVWR.

Against the 391T145: the Pinnacle 36KPTS is 35 lb lighter and 4 ft shorter; the Wolf Pack 411STAY is 75 lb lighter; the Bighorn 36RK is 85 lb lighter and 5 ft shorter. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest fifth wheels from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Vengeance Rogue floorplans profiled here run 5,498 to 14,014 pounds dry and 27 to 45 feet of exterior length across 12 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Vengeance Rogue line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 11 of them for the 391T145. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: interior height, sleeps, slide count, axle count, tire specification, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (85%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
