Excellent insight. I was only concerned at the time about the width fit in the wheel well. I never thought of the height, which is more important the longer the Airstream is. The good news is that I've gone over some pretty bad humps into gas stations, etc, with the Overlander and not dragged the tail end yet.
Now if the bolt pattern on my TV and the Airstream were the same (they are not), going to 16" wheels would allow just one spare...
