A 40×40 RV garage will provide you with approximately 1,600 sqft of interior space, which is large enough to be able to comfortably house many class A RV’s, such as the 2017 Forest River Fr3 32DS.
The benefit of using a prefabricated kit is that your RV garage could be up and running in under a few days, depending on the size of the kit as well as your experience.
This is because the parts that make up your RV garage will be manufactured elsewhere then brought to your location for assembly.
Steel is a robust and reliable material, with weather resistance.
