Thats what I've been thinking lately too. She gets 12mpg though, for an aerodynamic nightmare that's not bad. I may switch things up in the near future. Maybe I can talk you out of one of those 2 man rigs for my F350. The kids love the Isuzu, they would be pretty upset if I got rid of her. Thanks Splash, I will try to keep in touch on this one from time to time. You love those NPR's too, you are definitely set-up and ready to wash.
Id keep the NPR for the powerwashing stuff and industrial cleaning. Then do a nice SoftWash Systems truck for the residential stuff. In Talie you should be able to keep a SoftWash rig doing about $200k a year standing on its head in residential.
