I hope i can explain this. i thought it would be great to get another rear part of the cab and turn it around and fabricate sides and then get another one and mount in the rear for a door. it would seem if the cab came all the way back to the rear of the truck. i wish i could use photo shop too illustrate what i mean. most toppers or camper don't seem to fit the contours of the AD's. the tear drops seem to fit the era but i am a bit claustrophobic and it don't know it i could sleep in one. i did see one with a pop up top that a six footer could stand up in.
