So quick update. In contact with United Carports as recommended.
My size restrictions have me limited to 13' wide. I'm going 40' long. Now....12' legs is max before price starts to jump...it was recommended going 14' and it is an option ( I'm not limited by anything but my pocket book) so trying to figure out where my money goes furthest. The rear will face south and west side will have my house blocking about 32'....pay to have the rear enclosed and part of the west side. My neighbors home will block most all of the east but it will be open to elements. I think two panels will bring it right down to the fence line IF. I keep it at 12' tall....otherwise they would charge for three panels.
I've got $3500 to spend but can stretch it to $4000 if those enclosed options are worth it. FYI, my TC will be at the back and boat in front so the rv will be most exposed....and I'm ok with that. I do want to protect my investments.
