01 What makes it unique
The 37BEST is Wildcat’s flagship bunkhouse and the heaviest, longest, highest-GVWR coach in the line. It pairs a front king bedroom with bunk beds, a kitchen island and a full bath-and-a-half, opened by four slide-outs with dual entry doors, sleeping up to ten. At about 12,698 pounds dry on a 15,498-pound GVWR it is the most coach in the line. It rides the full Wildcat build: a 2-inch vacuum-bonded aluminum-framed sidewall structure, a one-piece molded fiberglass front cap, a PVC roof membrane with a lifetime warranty, a heated and enclosed underbelly with 12-volt tank heat pads and sectioned ABS armor, and 4-point automatic leveling.
Forest River publishes a 12,698-pound UVW, a 2,800-pound CCC and a 15,498-pound GVWR (the published GVWR equals UVW plus CCC exactly, the highest in the line), against a 2,210-pound dry pin. It carries the line’s larger 76-gallon grey and black tanks (matched to its bath-and-a-half). A 45,000-BTU three-air-conditioner system, a 35,000-BTU furnace, a 5,000-BTU electric fireplace, a 60,000-BTU tankless water heater, a 16-cubic-foot 12-volt refrigerator, a 21-inch 2-in-1 oven range, a 30-inch over-the-range microwave and a 60-gallon fresh tank are standard, under a 15-foot power awning with a 200-watt rooftop solar prep.
US street pricing has commonly run in the mid-to-high $60,000s and into the $70,000s. It is the flagship, do-everything bunkhouse Wildcat. For a family that wants a front king bedroom, bunk beds, a kitchen island and a full bath-and-a-half with dual entry doors — sleeping up to ten in the heaviest, longest, highest-GVWR coach in the line, towed behind a properly rated three-quarter-ton or larger truck — the 37BEST is the line’s flagship plan. It is sold as the Cardinal 37BEST under a sister badge.

03 The Wildcat floorplan family
Wildcat is Forest River's mid-profile affordable-luxury fifth wheel — a step above the brand's own value-mid Arctic Wolf and a step below its premium-mainstream Sandpiper. Six of the most distinct 2026 floorplans are profiled here in full. The 37BEST on this page is highlighted; each other plan links to its own page.
| Floorplan | Nominal | Sleeps | Notable |
|---|---|---|---|
| 32LIVE | 36 ft | 4 | Rear living + kitchen island + front bedroom, lightest and shortest, lowest GVWR |
| 33CHEF | 38 ft | 4 | Rear kitchen + front bedroom, couples who cook and work remote, lowest pin |
| 402BEDS | 42 ft | 8 | Two queen bedrooms + two full baths, dual entry, unique family plan |
| 36MB | 43 ft | 10 | Mid-bunk + loft family plan, fireplace, longest awning, highest pin |

Wildcat is Forest River's mid-profile affordable-luxury fifth wheel — a step above the brand's own value-mid Arctic Wolf and a step below its premium-mainstream Sandpiper. Ten of the most distinct 2026 retail floorplans are profiled here in full; only two Dealer Stock Only plans (34CRIB, 35FUN) are listed on the hub but not profiled. Every plan is built on a 2-inch vacuum-bonded aluminum-framed sidewall structure with a one-piece molded fiberglass front cap, a PVC roof membrane with a lifetime warranty, residential fiberglass roof and floor insulation, a heated and enclosed underbelly with 12-volt tank heat pads and sectioned ABS armor, seamless roto-cast holding tanks, 4-point automatic leveling, a 50-amp service, a 35,000-BTU furnace, an 18,000-BTU ducted air conditioner (a 45,000-BTU three-A/C system is standard on most plans), a 60,000-BTU tankless water heater, a 16-cubic-foot 12-volt refrigerator, a 5,000-BTU electric fireplace, a 60-gallon fresh tank line-wide and a 200-watt rooftop solar prep. Hitch weight, UVW, CCC and GVWR are published per plan; the published GVWR equals UVW plus CCC exactly on every profiled plan. The numeric per-axle GAWR is not separately published for Wildcat. UVW is a factory estimated average; real loaded pin weights run higher — always weigh the loaded coach and confirm against your truck's payload and rear-axle ratings. Wildcat is badge-engineered as the Cardinal under a sister badge.
04 What owners & reviewers report
Heaviest, longest, highest-GVWR coach in the line
At about 12,698 lb dry on a 15,498-lb GVWR and 43 feet 7 inches it is the most coach in the line — confirm your truck’s payload and rear-axle rating against the loaded pin.
Front king + bunks + bath-and-a-half
A front king bedroom, bunk beds, a kitchen island and a full bath-and-a-half with dual entry doors — a do-everything family flagship.
Larger grey and black tanks
A 76-gallon grey and 76-gallon black tank (versus 38 on most plans) matched to the bath-and-a-half — a real water-and-waste budget for a full household.
Slide count conflict logged
Several dealer listings describe the 37BEST as having "five slides" plus a "coffee bar"; the factory floorplan shows four slide-outs (dealers most likely count the king bed slide separately). This page uses the factory four-slide count; confirm the slide configuration on the specific unit.
05 How it compares
The two-bedroom alternative — two queen bedrooms and two full baths instead of a bunkhouse and a bath-and-a-half, also dual entry.
The lighter mid-bunk family plan — bunk beds and a loft on a lower GVWR than the flagship bunkhouse.
Forest River’s premium-mainstream full-size fifth wheel a tier above — a richer construction and equipment package at a higher price.
