I had looked at that one...it's really not designed for automotive use.
Had no room left for a compressor- but wanted AC.
Found mine from a Canadian Company that makes them for Big rigs- as a lot of places are coming out w/ no-idle laws-So sleeping in the cabin is gonna be w/o AC unless you go electric.
The BTUs are around 3500- should be fine in my 71 Vette-
It pulls 37A full tilt and has a power supply designed for 12Volts-And looks like it should go in a car- not a refrigerator!!!
About $100 more than the one Jegs...
