Lets give the 6.2 diesel some love
My 85 3500 dually came stock with a 6.2 and turbo 400 and gets descent mileage if i dont push it too hard. she also packs a good load. the only addition i would like to make would be to bolt on a GearVendor behind the tranny and give this old girl a 6speed built specifically for this truck- Scrapman

Tire size question
A buddy gave me some 16"s off of his 08 chevy dually..stock tires they were 215/85/16 My 86 dually runs 235/85/16 but with spacers so tires dont rub with a load on the truck...with 215"s on i wouldnt have that problem of rubbing- Scrapman
