01 What makes it unique
Alliance RV’s 2026 Paradigm brochure prints a dry weight of 14,072 lb and a GVWR of 16,500 lb for the 340RL, with a pin weight of 2,706 lb. The brochure prints no cargo carrying capacity, so none is shown here, and none is worked out by subtracting one published figure from the other. The trailer’s own federal weight label, inside the door, carries its cargo capacity as built.
Alliance lists it under Paradigm fifth wheels in that brochure, at 37' 10" long, with 98 gal fresh, 106 gal grey and 53 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank adds roughly 813 lb before anything else is loaded.
Among the 9 Paradigm floorplans whose dry weight Alliance’s 2026 brochure prints, it is number 3 by dry weight, in a range from 13,193 lb to 15,636 lb. Every figure in that comparison comes from the same brochure, for the same model year.
Every number on this page is read from Alliance RV’s 2026 Paradigm brochure (marked “New for 2026”, print date 19 September 2025). Alliance does not print exterior height or width, sleeping capacity or tire size against this floorplan there, so those rows read as not published.
How the 340RL differs from the other eight Paradigm floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 14,072 lb: third-lightest of nine, between the 310RL (13,525 lb) and the 382RK (14,812 lb).
- GVWR, 16,500 lb: third-lowest of nine, between the 295MK and 310RL (16,000 lb) and the 370FB, 375RD and two others (18,000 lb).
- Length, 37 ft 10 in: third-shortest of nine, between the 310RL (34 ft 11 in) and the 370FB (40 ft 4 in).
- Pin weight as a share of dry weight, 19.2%: fourth-smallest of nine, between the 385FL (18.9%) and the 295MK (19.5%).
- Pin weight, 2,706 lb: fifth-lightest of nine, between the 310RL (2,674 lb) and the 385FL (2,952 lb).
Next to the 310RL, the nearest lighter floorplan by dry weight, the 340RL is 547 lb heavier by dry weight, has a GVWR 500 lb higher, has a pin weight 32 lb heavier and is 2 ft 11 in longer; the two publish the same fresh tank, grey tank and black tank.
Next to the 382RK, the nearest heavier floorplan by dry weight, the 340RL is 740 lb lighter by dry weight, has a GVWR 1,500 lb lower, has a pin weight 329 lb lighter, is 3 ft 8 in shorter and has a black tank 53 gal smaller; the two publish the same fresh tank and grey tank.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (16,500 lb) and the upper loaded pin estimate (4,125 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.
03 The Paradigm floorplan family
Alliance RV’s 2026 Paradigm brochure lists 10 floorplans; this site profiles every one whose dry weight it prints. The brochure prints dry weight, GVWR, hitch weight, length and tanks, and no cargo carrying capacity.

04 Notes on this floorplan
What Alliance RV does not publish for the 340RL
No cargo carrying capacity, exterior height or width, sleeping capacity or tire size is printed against this floorplan in Alliance’s 2026 brochure, so those rows read as not published. Nothing is filled from a sibling floorplan, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
05 How it compares
13,525 lb dry and 16,000 lb GVWR, against this plan’s 14,072 lb and 16,500 lb.
14,812 lb dry and 18,000 lb GVWR, against this plan’s 14,072 lb and 16,500 lb.
07 Where this floorplan sits
Closest sibling: the Paradigm 310RL, nearest on the published figures. It differs on 4 of the 7 fields both publish (this plan first): length 37 ft 10 in vs 34 ft 11 in; dry weight 14,072 lb vs 13,525 lb; GVWR 16,500 lb vs 16,000 lb; hitch weight 2,706 lb vs 2,674 lb. They match on fresh tank, grey tank and black tank.
