Hi Steve, we're up North in Arizona off I-40 near Flagstaff. I definitely think there's a market for that. Check out the Cobbtown Acres location on Facebook or here:
https://cobbtownacresllc.com/ They are pretty new and already often filled to capacity.
We looked into leasing the old Camping World building in Bellemont, just West of Flagstaff, which has 6 bays and has been vacant for a few years. But they want...drum roll...$30,000/month. So that's not happening! But we're actively looking up here. So, I think your vision could be viable.
