RV garage dimensions
Size the building from your own RV's published height and length, not from a class average: the door has to clear roof-mounted equipment, and the depth has to clear the hitch.
- Class B height
- 9′ 4″ published
- Class C height
- 11′ 0″ published
- Class A height
- up to 12′ 6″ published
- Longest listed
- 36′ 11″

Published RV dimensions and the building they need
Footprint = published envelope + stated allowances; door height = published height + 1 ft
| RV | Class | Length | Height | Minimum footprint | Minimum door height |

| Winnebago Minnie Winnie 22R | Class C | 23.83′ | 11′ | 12.46′ × 27.83′ | 12′ |

Lengths, heights and widths are published Winnebago specifications. The allowances are stated inputs, listed below.

Air conditioners, satellite domes and solar mounts sit above the published roof line. Measure your own before ordering a door.

Planning
Length margin is where plans fail
Published length is the coach, not the coach plus a tow hitch, a bike rack or a person walking round the back to close the door. A 36 ft 11 in Adventurer 36Z in a 40 ft deep building leaves 3′ 1″ in total — less than a walkway once the door track is in. At 45 ft of depth the same coach leaves 8′ 1″.
Every margin above is the building dimension minus the published RV dimension. Substitute your own model's figures and the arithmetic is the same.

What fits around the RV
Common RV garage requirements against the published figures
- Fits
Walk both sides with the slide-outs in
A 2 ft side margin each side clears an 8 ft 5.5 in coach in a 12 ft 6 in wide bay.
- Marginal
Operate slide-outs inside the building
Slide-out projection is model-specific and is not published as a single figure. Measure yours.
- Fits
Store a car alongside a Class C
A 30 ft wide bay parks an 8 ft 5.5 in coach and a 6 ft 6 in car with room between them.
- Does not fit
Clear a 12 ft 6 in coach under a 12 ft door
Negative margin before roof equipment is even counted.

Answers
Common questions
Take the published height of your RV and add an allowance for roof equipment. A Class C at 11 ft with a 1 ft allowance wants a 12 ft opening; a 12 ft 6 in Class A wants 13 ft 6 in. There is no single answer that covers both.
Published length plus a walk-around margin. A 36 ft 11 in coach in a 40 ft building leaves about 3 ft 1 in in total, which is not enough to walk behind it comfortably.
Published RV width for the coaches listed here is 8 ft 5.5 in. With a 2 ft side margin each side that is a 12 ft 6 in bay before any storage along the walls.
No. They are published Winnebago specifications for named floorplans. The allowances added to them are stated planning inputs, shown separately so you can substitute your own.
