I just bought this 1986 GMC Sierra Classic 2WD crew cab dually as a project truck. It has 182,000 miles on it. The 454 and transmission have already been rebuilt. What were some of the problem areas with this truck? What should I check/replace?

Body rust usually is an issue although yours appears to be solid.....shine it up and drive it!...Fred

Thanks fred...

This truck had Ziebart several times and the body is solid except for the rear corner of the cab on both sides.

One option that I like is the "heavy hauler" two-ton package. I wonder what the towing capacity is on this thing?

They will pull a house!....does it have a 4:10 gear in the rear?...what are you pulling?....Fred

Yes...it has the 4:10 gear ratio. I will be pulling a Formula 292 FASTech (approximately 9000 pounds).

it will pass everything but a gas station, good trucks but better if you update trans to a 4l80e. the have wiring kits for it
