I can never seem to get anyone to acknowledge this on TTR, but the battery APUs on the Prostars are garbage. I'm lucky if I can get 10 hours of heat out of them.
Over their C15 Acert's that had DPF mufllers in 2010. The ones that had spark plugs in them to regen.
I bought one of the new LTs with their A26 motor recently. I've put 18,400 miles on it and I'm very pleased. They weren't on my list originally but they were the only ones that would build what I wanted. I've driven Prostars before when I was at Knight with Cummins and Maxxforce. My previous truck had a Cummins in it too. These new ones are so much better than the Prostar and the A26 motor has been outstanding so far. I'm a one truck guy and I'm very pleased with it.
You can get it, but you will have to other it that way, if they refuse to do it, then you will have to do it with one of the companies that install the glider kit
