My feelings and opinion is that of how the customer sees you and you're vehicle when you pick up or deliver. We are there to service them, and I feel they will feel more comfortable knowing it is the right van for the job, not looking tacky, and properly labeled.The same with the driver, and his personal hygiene. Do you feel more comfortable buying an alternator from Napa, with a warranty, or from a junkyard, wondering just how long it will last? Please don't get offended, but this window van thing kinda reminds me of the Clint Eastwood movie "Any which way you can" where the one guy is sitting in his beat up tow truck, listening to the other towing companies dispatches on the radio, and he says I can get there faster and goes through several towing company door magnetic signs, and slaps the appropriate one on the door and takes off....lol..I'm not saying window vans and their drivers are fly by night operations, but it just looks so much more professional when the appropriate vehicle pulls up to the customer, in my opinion...
