Yup.
Ten years ago when the truck was parked, a beat up GMT400 farm truck was utterly worthless. The only thing of value was the motor. He never intended to get it back on the road. Instead he filled it with scrap metal and trash and intended to roll it off into a ditch somewhere. It's pretty common around here. Another guy I knew bought 10 acres near me and discovered two cars on the property with no documentation. He had a ditch that needed filled. I can guess where those two cars went.
I have another coworker with a 3/4 ton frame, engine, transmission, and suspension that he's offering me. I was already interested because I'll need a motor, but now I'm more interested. My only concern is that I think that's a 4wd frame, and for a long-haul truck I'd prefer 2wd for fuel economy and simplicity. I'm also not set up for a cab swap; I'd have to borrow an a-frame. If I get the 3/4 frame, it might become a crossmember donor, but then my problem is that I don't have the shop wired for 220v yet. I think I found my driving motivator for that!
Ugh. Frustrating, but all this typing is helping me sort the problem and come up with a plan. I'm going to go ahead with disassembling the dash and cleaning that mess up. It's something I can tackle this weekend and it's going to need done eventually anyways.
