This is honestly pretty inaccurate.

I have done the car rental thing and the truck rental thing, and truck is a much better place to work.

Since Truck only deals with business clients, a lot more attention is given to account relationships. There are no up-sells or DW/SLP/PAI sales as the accounts are setup and negoitated in advance.

Truck branches do not need to run as tight as car, and everything is done on strict reservation basis. So there is actually time to run/grow the business as opposed to scampering around in panic mode trying to help retail customers into cars you don't have.

There is a lot more marketing in the truck division, and a lot less beraucracy.
