I think this is spot on. I have the same carport. It used to flex in the wind before I welded steel gussets to the corners to stop that. But the roof sheeting started to tear around some of the screws because of the movement. It’s a pain but I think the best option is to remove the roof panels, then move the carport. It will be a lot lighter and easier to move also and no chance of structural damage.I'd look on line for a similar carport to see what the shipping weight is.
I don't think weight will be your issue. The issue is that moving it will cause the frame to flex possibly tearing the roof around the fasteners unless you can figure out a way to stabilize it and go very slowly over a short distance.
Build a BIG skid and anchor it to skid and tow it by the skid...
Yes, and I am pretty sure that the roofing panels will get widened or torn at the screws fastener locations by moving. Then it leaks everywhere.Those carports aren’t that hard to disassemble. I might consider putting a piece of lumber at both ends for a spreader to keep the legs spaced apart and drag it but much beyond that you’d be faster to take it apart.
