01 What the Bighorn line is
Bighorn is the luxury tier of Heartland's relaunch — the full-profile fifth wheel above the laminated North Trail and the value Prowler — and on the 10 July 2026 RVUSA probe it carried 140 active listings. The 2026 roster runs seven floorplans from the 36-foot 31RL to the 43-foot-10 39FL and 40DB, with factory Base MSRPs from $107,475 to $134,175, and every plan publishes a weight set that sums to its printed GVWR exactly.
The construction is full-profile luxury hardware: a 102-inch-wide body on a 12-inch I-beam frame with a drop-frame storage bay, a painted fiberglass front cap with automotive clearcoat and LED accents, CoreShield gel-coat laminated sidewalls, the TrussXL truss under an Alpha PVC roof with a limited lifetime warranty, and the ThermaShield zero-to-one-hundred-degree package backed by a 40,000-BTU furnace and dual 15,000-BTU Whisper Quiet air conditioners. The mandatory Premium Package — six-point hydraulic auto-leveling and much of the residential equipment list — is baked into the factory Base MSRP, so the placard prices here already reflect the equipment every unit ships with.
One pricing note, logged rather than hidden: dealer window placards (base plus freight, prep and options) run well above the factory Base MSRP — 39RK placards of $144-146k against its $123,975 base — while advertised street prices run well below it. The factory Base MSRP is the one apples-to-apples figure across the line and it is what the table below shows; confirm both numbers with a dealer. RVUSA's price records also lag the current factory figures by about $2,250 line-wide, and its width field still carries the stale 8-foot figure against the factory's 102 inches — factory figures are used throughout.
02 All seven floorplans, profiled in depth
This is the complete 2026 Bighorn roster — the rear-living 31RL entry, the rear-kitchen 36RK, the middle-den 37MD, the rear-entertainment 38RE (the most-listed Bighorn on the probe day), the five-slide front-living 39FL, the stretched rear-kitchen 39RK and the two-bedroom 40DB. The table is sorted by dry weight.
| Floorplan | Base MSRP | Dry wt | GVWR | Length | Sleeps | Layout |
|---|---|---|---|---|---|---|
| 31RL | $107,475 | 13,060 lbs | 16,000 lbs | 36' 0" | 4 | Rear-living entry — shortest, lightest, friendliest pin |
| 36RK | $121,793 | 14,465 lbs | 17,300 lbs | 40' 5" | 4 | Rear-kitchen plan — the galley takes the back wall |
| 39RK | $123,975 | 15,200 lbs | 18,200 lbs | 43' 3" | 4 | Rear U-kitchen, bath-and-a-half — respec’d stretch; best margin |
| 38RE | $128,175 | 15,275 lbs | 17,995 lbs | 42' 6" | 4 | Rear-entertainment quad-slide — most-listed; 137-gal grey |
| 39FL | $134,175 | 15,645 lbs | 17,995 lbs | 43' 10" | 4 | Front-living flagship — five slides, heaviest pin |
| 37MD | $126,225 | 15,650 lbs | 18,100 lbs | 42' 10" | 8 | Middle-den quad-slide — two living zones |
| 40DB | $132,975 | 16,110 lbs | 18,850 lbs | 43' 10" | 8 | Two bedrooms, two full baths — the multi-family flagship |
This is a published-GVWR-clean set: dry weight plus cargo capacity equals the printed GVWR exactly on all seven plans. Three provenance notes, logged. First, RVUSA and the early-2026 print brochure carry a stale weight set on five plans (36RK, 37MD, 38RE, 39FL, 39RK); the June-2026 dealer-network brochure matches the current factory pages to the pound, so the factory figures shown here are tri-source confirmed. Second, the 39RK was respec'd mid-cycle — the early print shows a 40'4″ / 14,080-lb unit, the current factory page and June brochure print the stretched 43'3″ / 15,200-lb three-slide unit shown here. Third, sleeps counts are the factory's “up to” figures; where sources disagree (36RK, 39RK) the factory figure is shown and the conflict logged. Always confirm against the unit's weight sticker and your truck's payload placard before towing.
03 What is deliberately not on this page
Heartland also builds the Bighorn Traveler — a separate, lighter sub-line sold under the Bighorn name with its own distinct floorplans, weights and pricing. It is excluded from this reference rather than mixed in: attributing Traveler weights to Bighorn-proper plans (or the reverse) would corrupt both records, the same reason West-edition twins are excluded elsewhere on this site. The seven plans above are the complete Bighorn-proper roster; a Traveler profile would be its own hub if demand warrants one.
04 How to choose & what to weigh
The 38RE is the plan the market picked
The most-listed Bighorn on the probe day at 31 active listings: a rear entertainment wall, four slides, dual 17-foot and 15-foot awnings and the line's biggest grey capacity at 137 gallons — a full-hookup entertainer's spec on a 15,275-lb dry / 2,970-lb pin ticket.
Front living or rear living is the real fork
The 39FL is the flagship statement — front living room, five slides, the line's top Base MSRP at $134,175 and its heaviest pin at 3,090 lb. The 31RL makes the opposite case: the classic rear-living layout at the entry price ($107,475), the lightest dry weight (13,060 lb) and the gentlest pin in the line (2,405 lb).
The 40DB is the two-household plan
Two bedrooms and two full baths, sleeps up to eight, a 100-gallon black tank and 120 lb of propane — drawn for two couples or a big family full-timing. One equipment note: it is the only Bighorn where the rear 3,000-lb tow hitch is not available.
What to verify on the lot
Pin weight is the whole ballgame: dry pins run 2,405 to 3,090 lb, and a loaded pin will land well above that — run the math against your truck's payload placard, not its tow rating. Cargo margins run 2,350 (39FL) to 3,000 lb (39RK). The line rides 17.5-inch Load Range H commercial tires on 8,000-lb axles (7,000-lb on the 31RL); verify placard prices against the $107,475-$134,175 factory bases, since dealer windows run higher and street deals run lower.
05 What every Bighorn has
06 Where Bighorn sits in the luxury fifth-wheel field
Inside Heartland, Bighorn is the top of the relaunch ladder — the fifth wheel above the laminated North Trail and the value Prowler travel trailers. Across the aisle it fights the crowded full-size luxury class: Keystone's Montana (its stablemate under THOR), Grand Design's Solitude and Forest River's Cedar Creek and Sandpiper all sell at the same lengths and prices. The Bighorn counterargument is equipment honesty: the mandatory Premium Package is priced into the factory Base MSRP rather than stacked on the window, dual Whisper Quiet air conditioners and the 21-cubic-foot GE fridge on an inverter are standard, and the weight table sums to its printed GVWR on every plan.
