Looks like we have some time to brainstorm this cover thing. And, they do design some of these steel framed and roofed covered shelters to withstand 100 mph winds.
From what I’ve read in the past, they can be bought as kits and bolt together. A good concrete pad should have enough weight to hold it in place.
I saw the one below in Riverside a few years back and took some pictures for reference.
I don’t know all the sizes available, but this one looked pretty hefty with 3-4′ square tubing frame work. Plus it was all galvanized & it looked like it was all just bolted/screwed together. No painting down the road.
You know what they say, “Go big or go home”!
