i have one in my LR3 and love it! the backseat in the LR3 consists of 3 individual folding seats. i took out the center seat and have the fridge bungy strapped down between the two side seats. it fits perfectly. i have a dual battery setup and run the fridge near full time. i still haven't figured out how i am going to set it up in the new wrangler. i think i am going to have to stick it in the back. i totally recommend the fridge.
