1998 4.2. A/C is completely shot. I need a complete overhaul, evap, dryer, compressor etc. I do alot of mechanics on my own but this one is over my head. It is about a 1500 dollar job. I know this this idea would be ugly but I have been looking onto under the dash a/c kits

They run around 500 bucks and I do not have to remove my dash board. What do you guys think? Has anyone ever done this? I am the only one that drives this truck it is my second vehicle but I do use it often. Miami is real hot!! Any other ideas? I am about to get a wall unit with a generator in the back bed lol!
