Never seen a white one before, that's rare. So much better than yellow/tan with 70's graphics. Looks like maybe an engine fire happened -- flat black under the hood, engine parts painted, new hoses... the hood looks repainted maybe, no exterior photo of it. Or driver's side of the truck.
Furnace under the sink it appears.
No overdrive, or cruise control. Not having those makes driving less enjoyable. Plan on 8 mpg, that way if you get 10 or 12 it will make you happy.
Nonetheless, someone should call on it. Salvage title? Long term... GM diesel, relevant suspension upgrades, overdrive automatic -- and it would be ultimate. It already looks awesome.
