Not my first dually but it is my first square Chevy. 88 GMC. It's not perfect but everything except one electric door lock works. Plans are clean it up, dry up some oil leaks, exhaust and lower it some.
Most of the time I'll use it to tow my 64 Chevy II in a 24' enclosed trailer. Ahhh, Who am I kidding, I'm going to drive the crap out of it.
