I appreciate the comments, but I'm more curious which ones you would pick from the two I gave. As I mentioned before to get a nice one installed that is set to our wind rating is about $15,000. You would need engineering for the base and the carport. This means your pouring concrete with rebar. So you can not use an existing driveway or just plop it on the grass. So thats why Im leaning toward a non permanent solution, which bypasses these requirements. I understand they may only last a few years, but at that point I may be in a different RV or move houses etc. Not that Im planning on it, but things happen. Both of these I can have shipped an assembled for under $3000. I can replace quite a few times for the cost of a permanent one without the headache too.
