I'm about to pull the trigger on aftermarket AC, and I am leaning toward Classic Auto Air, but I'm not completely fond of the "ecu" part of it. Proprietary black boxes tend to get very hard to find as things age. But I like the look of the new AC controls. Old Air products seems to be the dark horse here, but looks like a decent system. If you have recent experience, please let me know what you went with, and how it went. I am an experienced tech, with the right tools to complete the job myself, but I'd rather have pre-made hoses. Otherwise, it leads to finger pointing. My cab is a non-ac cab, but I would like to buy the factory looking vents and install them. Please, give me your opinions on these, not "retrofit a factory unit because it's better". I want a kit that comes with everything, that won't nickle and dime me and take 3 months to find all the little bits.
