I have been watching how much I idle. I ususally run the truck with the air on high for about an hour then I shut it off and go to bed. It doesn' stay cool in here for the whole night but it helps. Our company also reimburses one motel room a week so we have also been taking advantage of that. It has been fairly cool so far so there have been a lot of nights just rolling the windows down has been nice.
Depends on the outside temp, depends on if I run the truck or not. Last couple of weeks have been nice at night to sleep without the truck running. If I'm unloading at a stop or P/U a backhaul, then the truck is OFF. We have no idle restriction nor computers in the truck that track us or our idleing. All they have said to us was that if we need to idle to sleep, do it. Just turn the trucks off at the stops. If fuel keeps rising though, they are thinking off dumping the sleepers and getting us daycabs(there are only four of us that use sleepers).
