1972 Chevrolet 3/4 ton Camper special Fully loaded with all options, 72k miles

My cousin bought this truck brand new to use on his farm. It sat more than it was used. It is a fully loaded camper special. Original 400 motor, original paint and interior. Please see the glove box tag for all the options he ordered. Truck runs and drives very well. Please call me with any questions.
