I got a couple of quotes from the lumber yards on roof trusses, as well as everything else I would need for a 14'X24' "polebarn" style carport. I called my grandfather to tell him I'd be coming up in a couple of weeks to help him out a bit. I was hoping to keep it a surprise by not telling him exactly what I was doing.
Well, he asked me, "while your here, can you help me put up my canvas garage that I bought last spring?"
Well, since he already bought the Shelterlogic, I ended up giving up on my idea (for now anyways) of building the carport, and instead just built a proper "foundation" base for the fabric carport.
I ground up a couple stumps for him, installed some drainage pipe and crushed stone (it was a wet area last winter), dug some holes for Sonotubes (4 per side), spread 12 yards of gravel, put a pressure treated sill down both sides, and assembled and raised the portable garage. He is happy with it so that is all that matters, but I told him if it doesn't last his winter, I'm putting up something a little more "appropriate" for the NH winters.
Here are a few pics of the process....
