I'm looking at a clean 1 owner '04 chevy 4wd dually extra cab. I has around 44,000 miles on it, Duramax/Alison, cloth interior, pw, pdl, ac, cruise, tilt. It has a Myers plow on it but was only used to plow the previous owner's business lot. Asking 22k for it. What do you think it's worth? I'm trying to find a dually to possibly put a dump body on it. I've been trying to find a decent extra cab dump, but I'm not having any luck. Any ballpark figures on an 8' mason dump or dumping flatbed installed? Thanks!
