I skimmed through the site Mike - it will require a closer look. I noticed a 10% charge to the renter on booking - not sure if that is just for a deposit or if that is addition to the 25% commission charged to the owner on rental.
How does it work for AirBnB?
Corky, one major difference though -
Uhaul owned the trailers - these guys are merely facilitating the rentals for owners.
