The two air conditioning choices I know of are Vintage Air and the one from CCOT. I have seen and operated a Vintage Air unit in an FJ40. It cools really well but I do not like the large size of the unit. Also I would like to keep my original heat set up. The CCOT unit I like the pictures on their site of the air conditoning they offer. Normally I do not like the quality of their parts. Anyone have any experience with a CCOT unit??
