Planning Your RV Garage

SteelMaster will help with the specific engineering and blueprint-related details of your building, but before contacting us, you should have a general of what you want out of your RV storage.

Step 1: Determine garage dimensions needed for RV

Step 1: Determine garage dimensions needed for RV

Class A, B, C, and travel trailers can all be accommodated in a steel RV garage kit. RVs typically range between 20′ to 45′ long, 8′ to 10′ wide, and 10′ to 14′ tall, so you will need a building at least a bit larger than those dimensions.

Step 2: Select how much extra space you’ll need

Step 2: Select how much extra space you’ll need

If you want to store more than just your motorhome you can choose an even larger building. Here are the most popular RV garage sizes for each Quonset hut model:

  • A-Model: 20’W X 16’W X 36’L*
  • Q-Model: 35’W X 18’H X 50’L
  • S-Model: 30’W X 15’H X 40’L
  • X-Model: 30’W X 19’H X 50’L

Our metal RV garage kits are easy to build

Every steel panel of your Quonset RV Garage kit is pre-drilled and pre-punched — the entire building only requires one size nut and one size bolt. All you need are a few tools, a few friends, and a few days to put together your SteelMaster Quonset Hut.

Pre-construct your arches

Lay the arches of the building out on the ground and hand-tighten each panel together. You’ll want to decide if you’ll be raising the entire arch or half of an arch at a time and pre-construct the arches accordingly. For larger buildings, it often makes sense to raise a half arch at a time.


Raise & connect the arches

Now that the arches are mostly assembled on the ground, raise each of them, and connect them to any foundation you need — our arches can be put on shipping containers, on the ground, or anchored to a concrete foundation. Then, connect the arch to the previously raised arch.

Tighten the bolts as you go

Once four arches are up, go back and fully tighten the first arch. Then each time you raise a new arch, go back and tighten the arch that’s four arches back.

Install endwalls

Now that the building has been erected, install the endwalls you’ve selected for the garage. A popular option is to use steel endwalls provided by SteelMaster as they are functional and economical.
