No idea where you are getting the 80 lbs of ice, these things hold ?? a gallon - gallon and a half unless you are talking about their largest model which you ain't gonna get inside your car (you going to remove the rear seat?)
So why did you ask? So what you are saying is, you are really a schill for the company, right?
I have better things to do than to carry a tub of ice water around in my car., and I have better things to do than to talk to people like you
