Well we got a load yesterday. It took us all of 75 miles and for some damn reson my trainer wanted to get her 14 hours early for delivery. So therre I was sleeping in top bunk with the optimized idle on. Optimized ideal works like this you set the desired temperature in truck turn it on and it will turn the truckon and off to try and maintain that temperature, the other reason it turns the truck on is to charge the batteries. The sleep was aweful its shacking every time it does either. There is most likely a bad battery in the truck (it has 4 of them) so most of the times it turned on was to charge batteries!!! Also we were parked at a closed warehouse. Making useing the bathroom a Challenge!!! And I had to walk a half mile to get coffee this morning!!!!
