Supr it is amazing how we never seem to discover what we have right near us until it nolonger is! By the way tell your son Semper Fi and thanks for his service!
I agree with the others, while stationed in NC I did plenty of bonzi runs with how many miles can I cover, continued after my service when I took MC vacations. Always said I had to go back to work to rest afterwards.
One other thought are you buying a new RV? If so can you pick it up in AZ? Then you fly out or even dry what you are planning on towing out and only drive the RV home.
