1981 GMC Sierra Grande 4x4 Pickup Truck

1981 GMC Sierra Grande 4x4 half ton. Top of the line trim level in 1981. Gem Top GT insulated canopy on the bed. Two gas tanks. Engine replaced several years ago with a Goodwrench 350. The pickup bed was lined with carpet in the 80’s and used for camping. There is plywood under the carpet but the bed underneath looks great. Canopy has been on the truck since new. I’m the third owner but previous owner bought it in the early 80’s and drove it for years. Never off roaded or used as a farm truck, all highway miles. Actual mileage unknown. Paint has worn off the hood and roof. Surface rust in places. With a new coat of paint and a little upholstery work truck would look great. Just drove it sixty miles the other day with no problems. New fuel pump installed last summer.
