Very interesting bed set up William! I've never seen a power washer running a service bed, it sure looks like it works though for what you're doing. What trucks do you run? I couldn't tell from that back window. I decided to run 80-86 F250 regular cab long beds for house washes and roof cleaning. I'm picking up another one soon to start going through. I'll pick up a few 1991-2002 15k gvw C3500HD's chassis cabs when I get around to fleet washing. I'd like to find some older International 4700 21.5k gvw low pro's but where I'm at they are rare rare rare and besides it would only have the t444e and not the DT466. Older F550's are out as they are way too much money for the purpose they will be serving.
