RV Heights Class A or C for new shop door ?

[Thats a RRRV]

Building a new shop and would like to know the highest any class A and Cs are . So I can build shop with the tallest door in it ? So I dont make door to short for future coaches ?
Thanks

16’ door will cover you. I actually looked into it when we built 2 years ago. The lot isn’t wide enough to take the house my wife wanted with an attached RV garage. Our HOA covenants are ridiculous for out-buildings, so I can’t afford a detached one right now.

Depends how much extra room you want up top, 13'-6" is the legal max height for an RV

I don't know if maximum heights include the AC units. I think 14 would be safe, but we need a few class A guys to chime in to see if that's enough. Twelve foot covers my Greyhawk including AC with inches to spare.
