"I own seven premium Willis units and two compact Willie units. Dollar for dollar, this is the best unit. Nothing on the market is as efficient on fuel. I've tested a competitor on my trucks and the Willie still burned significantly less fuel in an eight hour period. I have to go by what I see and what my drivers tell me, and I've done a lot of research. You pay for what you get... this is the only APU that gets my trucks below 72 degrees on the hottest day of the summer."

"There is no other system that cools like a Willis! Period! It also maintains battery strength, supplies ample heat and allows me to rest comfortably in the far out places that we, as drivers, venture."
