2026 Highland Ridge Open Range 3X393TBR

The Open Range 3X 393TBR leaves Highland Ridge's factory at 15,260 lbs dry, with a published GVWR of 17,700 lbs and 2,440 lbs of cargo capacity between the two. Cargo capacity is 14% of the loaded rating, and Highland Ridge'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 75-gallon fresh tank spends 622 lbs of that 2,440 lbs before anything else is loaded.

Dry pin weight is 2,900 lbs, which is 19% 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 2,900 lbs over the bed. Read the payload figure on your own door sticker rather than a brochure maximum for the model.

Tank capacities are 75 gallons fresh, 97 grey and 80 black, 177 gallons of waste capacity against 75 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. Highland Ridge publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.

Against the rest of the Open Range 3X roster this is the 3rd of 3 floorplans by dry weight, in a line that runs from 11,670 lbs to 15,260 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 15,260 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 16,480 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 17,700 lbs is a limit rather than a target.

Every number above was captured twice from Highland Ridge 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 0 shared figures agree could not be compared 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 Highland Ridge does not publish it in this channel, not because it was hard to find - and the row says so rather than being quietly dropped.

Highland Ridge 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. 393TBR is a Open Range 3X designation and this site does not decode it into a layout claim.

Open Range 3X is Highland Ridge's heavy fifth-wheel roster and the top of the whole catalogue by weight. Three floorplans are published for 2026 and all three are profiled, 11,670 lb to 15,260 lb dry across 34 to 44 feet, with dry pin weights of 2,375 to 2,990 lb. A 2,990 lb dry pin is a three-quarter-ton-and-up figure before anything is loaded, and it rises with the trailer. Dry weight plus cargo capacity equals the published GVWR exactly on all three.

This floorplan carries its water comfortably. A full 75-gallon fresh tank is roughly 26% of the 2,440-pound cargo capacity, leaving the 393TBR with a usable gear budget even when you tow full.

The published dry pin weight of 2,900 pounds is 19% of this floorplan’s 15,260-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 17,700-pound GVWR the 393TBR is towing 2,440 pounds more than its 15,260-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 75 gallons of fresh against 97 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 3 Open Range 3X floorplans profiled here, the 393TBR carries the highest GVWR at 17,700 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: Open Range 3X 372MBH is 1,400 pounds lighter at 16,300 lb GVWR.

Against the 393TBR: the Pinnacle 38KPTS is 3 ft shorter; the Model Z 3420 is 5 lb lighter and 4 ft shorter; the North Point 387FBTS is 50 lb lighter and 1 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 Open Range 3X floorplans profiled here run 11,670 to 15,260 pounds dry and 35 to 44 feet of exterior length across 3 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 Open Range 3X line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 11 of them for the 393TBR. 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 (100%) 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.
