I ordered a 17' truck with no extras for my move.  As anyone who has used U-Haul in the past knows, they often throw things like dollies and protective mats on the back of the truck which can be used for an extra fee.  Well, apparently this truck had a dolly on the back without a protective green seal to signify that it had not been used.  When I returned the truck later in the day, the attendant refused to believe the mistake could have possibly been on their end and charged me an extra fee for the use of the dolly, which I did not use.    \n\nMy advice to future customers:  always check the back of the truck before leaving the parking lot to avoid pointless fees.
