I have a VersaTube RV awning, 12' wide, 30' long,13' high, and it works great. All galvanized and made in the USA. My town gave me a permit and called it a pavillion. I had it installed on a 5.5" thick, reinforced concrete slab. The awning is rated for a snow load of 65 lbs. per at a wind load of 90 mph. highest requirement in NYS, by code. My TT is 102" wide and I have no problem backing the TT in and opening the door of the TT to access it. Also nice to be able to, maintain, work on, wash & wax TT under the awning.
Good luck.
