2014 Kenworth T680, manual transmission 10 speed, apu and solar panel, it been parked for 2 years, it had a problem that the speed would stay stuck at 40 miles an hour and would go back to normal. Parked to fix but never found the problem, the suspicion is that it could be the speed sensor, and the truck has no Def problem at all. Apu was 2 years old when I stopped with a very few hours. Title in hand and Truck doesn’t run … it need to be tolled out that’s why I’m selling that cheap. No delivery available. Open for offers
