The only reason they want pay that is b/c some mobile fleetwasher is doing them cheaper,they aren't smart enough to realize if no mobile around they would have to pay stand alone prices.Next time you drive by a stand alone truckwash look how busy they are.Look at all the company names on the doors and most of the trucks has a mobile fleetwasher at home base doing them cheaper.Fleet companys aren't going to drive a dirty truck for lone before it gets washed nomatter if its a stand alone truckwash or mobile they pay each his price.I think my service and wash job is as good if not better than a stand alone truck wash so why charge a cheaper price.
However I do understand the lower priced mobile guys as to not charge stand alone prices.

When In Doubt Think It Out
