Hi and welcome to mightyram. Looks like your truck has had quite a life. Good thing about TX is the climate. Not great for paint (or plastic/vinyl trim either) but less chance of cancer eating out a vehicle. It looks to be pretty straight for a work horse though. I hear you about the A/C thing, my city is competing for the title of 'hottest capital city on earth' and I felt lucky I found a gen 1 with dealership optioned Air International A/C. A big clean and a mechanical once over and your truck will be fighting fit. You'll be surprised how much of the dash and trim can be restored with elbow grease and tire shine.
