2026 Alliance RV Paradigm385FL

The 385FL inverts the usual layout: an ‘FL’ front living area sits up over the hitch as a raised great room, with a loft above, the kitchen amidships and a king suite at the rear. It opens on five slide-outs — the most in the line with the 375RD — and sleeps six. The equipment is the full Paradigm package: a Lusso range with a 12,000-BTU burner and a 3.73-cubic-foot oven, a 19-cubic-foot 12-volt residential refrigerator, a king bed and a fireplace, on the Benchmark 101-inch wide-body drop-frame chassis with Curt 8,000-pound axles, self-adjusting brakes and six-point hydraulic leveling.

Alliance publishes a 19,000-pound GVWR against the 15,487-pound dry weight, leaving a 3,513-pound cargo capacity — the largest in the profiled group — and a 2,957-pound dry pin. Three roof air conditioners totalling 40,500 BTU, a 40,000-BTU furnace, a 12-gallon gas/electric water heater, an enclosed and heated underbelly and 98/106/106-gallon fresh/grey/black tanks are standard. At a starting MSRP around $134,000, with street pricing below placard, the 385FL is the front-living Paradigm for buyers who want a raised front great room and a loft in a luxury full-profile coach, towed with a one-ton truck.

Paradigm is Alliance RV's luxury full-profile fifth wheel — the company's flagship since 2019 and a cross-shop against Grand Design's Solitude, Keystone's Montana and Jayco's Pinnacle. The 2026 line runs to ten floorplans; the six profiled in full are linked below and the four catalogued plans are shown muted. The 385FL on this page is highlighted.

This floorplan carries its water comfortably. A full 98-gallon fresh tank is roughly 23% of the 3,513-pound cargo capacity, leaving the 385FL with a usable gear budget even when you tow full.

The published dry pin weight of 2,957 pounds is 19% of this floorplan’s 15,487-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 19,000-pound GVWR the 385FL is towing 3,513 pounds more than its 15,487-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 98 gallons of fresh against 106 grey and 53 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 385FL sits 5 of 6 in the Paradigm line: 19,000 pounds against a line that runs from 16,000 to 19,000 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Paradigm 382RK is 1,000 pounds lighter at 18,000 lb GVWR; and Paradigm 388SP matches it exactly at 19,000 lb GVWR.

1 other Paradigm plan shares this floorplan’s 19,000 lb GVWR, so the ranking above separates plans that tow to the same ceiling. On a shared chassis the figure that actually differs between them is cargo capacity and where the weight sits, not the rating.

Against the 385FL: the Influence 3804DS is 1 ft longer; the Momentum 344M is 1 ft shorter; the Solitude 310GK is 7 ft shorter and sleeps 2 fewer. 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 Paradigm floorplans profiled here run 12,567 to 15,528 pounds dry and 33 to 42 feet of exterior length across 6 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 Paradigm line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 17 of them for the 385FL. 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, tire size (a tire description is published, a size is not). 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 (96%) 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.
