Nick, very easy problem to solve. I always had a pair of slip on sneakers at the entrance door. Janet made sure that I never wore them past the entrance steps getting back in the coach. The little bit of diesel odor was just the perfume that everyone should have in a coach. LOL
"AWW Nick, come on and quit being a candy Butt!"
If I remember correctly, You are the Candy Butt........."Candy Corn" LOL...
I have camped in busses since I was 3 years old. Campgrounds, Fields, Roadsides, Races, all kinds of refueling truck stops,ect..
I guess over the years I just became a little wiser. Why should I get dirty when I don't have to.
"It makes you feel kinda silly after a while if you step in dog crap everytime you walk out the back door" Even worse if you know ahead of time.
Just my way of thinking....
