1993 chevy Z71 4x4 extended cab

This is my dads truck, bought in 1993, garage kept. It has never been in an accident. I took it over a few years ago when he stopped driving. I used it as a daily driver (11miles) for a year or so, ended up buying a new vehicle and it has been rarely driven since. She has a couple little dings (tailgate, passenger door) but the sheet metal is in good shape. Paint is bad, florida sun has really beaten it up. Primer is good, a few surface rust spots starting to show up. Everything else is pretty good.
Extensive history of things being replaced or updated (included bag full of receipts, original window sticker, etc).
Tires are 18 months old, have about 1000 miles on them.
Z-bart undercoating every year while it was up north (no rusty rocker panels)
4x4 works, air is cold (haven't charged it ever, and it was converted to the newer gas while dad was still driving it). tranny rebuilt 5 years ago, new true locking differential in the rear, power steering pump, hoses, alternator, belts.
Has two captains chairs, super comfortable, with dual arm rests (dealer custom)
