I called to verify this earlier today and according to Penske they will NOT lease a truck to anyone that mentions Burning Man. In fact Penske corporate has provided their call center reps with a tip sheet for all Nevada rentals with questions to screen potential customers. They flat out do not want their trucks going to BRC.
If you want to find out more call them via the toll free number on their website but this is a shame as IMHO they have been the best company to rent from. They've always taken great care of me.
When you finally let go, only then will you learn how to live.
I bring order to chaos. And I bring chaos to those who deserve it.
