Their APU unit is very reliable. I’ve never had a problem with my auxiliary power unit. I have the APU serviced once a year when the truck goes in anyway. The APU helps save money on fuel, keep my truck warm, especially when I’m on the road overnight. The maintenance costs are really good. Definitely recommend their APUs.
We supply parts, and provide support for all prior versions of the Green APU. However today, the only unit we sell is our latest 5th Generation Kubota Star Edition APU.
