01 What makes it unique
The 36MB is Wildcat’s mid-bunk family plan and the one built for a crowd. It pairs a front king bedroom with mid bunk beds and a loft, a kitchen island, a rear living room and an electric fireplace, opened by four slide-outs, sleeping up to ten (Cardinal markets it as sleeping ten or more). At a 2,335-pound dry pin it carries the highest pin weight in the profiled line, and it tows under the line’s longest power awning at 19 feet. 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 an 11,537-pound UVW, a 2,798-pound CCC and a 14,335-pound GVWR (the published GVWR equals UVW plus CCC exactly, the highest GVWR of the lighter profiled plans), against the profiled line’s highest dry pin of 2,335 pounds. 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 two power awnings (19 and 11 feet) with a 200-watt rooftop solar prep.
US street pricing has commonly run around the high $50,000s. It is the mid-bunk, big-family Wildcat. For a family that wants bunk beds, a loft, a kitchen island, a front king bedroom and a rear living room with a fireplace — sleeping up to ten, towed behind a properly rated three-quarter-ton or larger truck — the 36MB is the line’s mid-bunk family plan. It is sold as the Cardinal 36MB 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 36MB on this page is highlighted; each other plan links to its own page.

|---|---|---|---|
| 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 |

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
Mid-bunk + loft family plan, sleeps up to ten
A front king bedroom plus mid bunk beds and a loft sleeping up to ten, with a rear living room and a fireplace — a full family coach.
Highest pin in the profiled line
At a 2,335-pound dry pin it carries the highest pin weight of the six profiled plans — confirm your truck’s payload and rear-axle rating against the loaded pin.
Longest awning + full three-A/C standard
The line’s longest power awning at 19 feet plus a 45,000-BTU three-air-conditioner system standard — a fully-cooled, shaded family campsite out of the box.
Four slides on a big floorplan
It opens on four slide-outs and sleeps up to ten, so confirm the live-in feel and the campsite footprint suit you before buying.
05 How it compares
The bigger bunk plan — a bath-and-a-half and dual entry doors, the heaviest and longest coach in the line.
The two-bedroom alternative — two queen bedrooms and two full baths instead of a bunk-and-loft layout, also dual entry.
Arctic Wolf’s most popular family bunkhouse a tier below — a lighter, lower-priced family coach with a leaner package.
