While NEVER stopped with my rv's, years and YEARS ago, I was actually stopped with my 'hippy-dippy' copper colored ford econoline panel van for passing the one exiting Florida on I-10.
Yes, I did have shag carpet in it and we all had long hair
but it was the wife, and two kids with me LOADED with luggage and gifts after a week at Mickey world...
They thought we were a commercial van as the suspension was down in the back from all them on the bed and the luggage
sent us on our way after seeing the kids and a quick scan in the back.
