Completely honest approach:
"Hi, I'd like to rent your motorhome..."
"Sure thing, where are you going with it?"
Oh I'm going to burning man, where i may likely "experiment" with illicit drugs, indulge heavily in alcoholic beverages, and hopefully get down with some wild sex acts that may or may not be even legal in the states
Anything other than that exact exchange would be a lie for just about everyone.....
