86,000 miles on this 454 big block Z71 with a manual 5 speed that has granny low

1991 Chevrolet Silverado Z71 extended cab with a long bed has the 7.4 liter 454 engine coupled to a 5 speed manual with granny low. Has 86,000 miles. Second owner, I purchased this from an estate. The original owner used it for a slide in camper and took really good care of it. It does have some blemishes...3 small cigarette burns (2 in the carpet and 1 in the seat), the headliner needs to be redone and the dash has 2 small cracks. The paint has a few minor nicks, but overall shines like new. There is one dent behind the passenger side of the cab I believe you can push out (paint less dent repair). It has aftermarket air assist bags on the rear springs and a receiver hitch. The tires are 11 years old, but have plenty of tread. The battery is 14 years old but still starts it like it should. I had the A/C converted with all the details; new valves, orifice tube, dehydrator/drier, etc., and it blows 38 degrees even when it's over 100 here in Arizona!!! The truck runs and drives like a new one.
