When I was an otr driver I would idle my engine over night to keep warm in the winter and cool in the summer. I would bump the idle up to 1000 rpm. I never had any problems with my engines. Many drivers never shut their engines off from the time they leave home until they come off the road for their time off. Of course there may be differences in big rig engines and RV diesel engines.

I did that back in the '70s and '80s too. And it wasn't good for the engines back then either. But at the money we made, one didn't mind the boss paying the heating bill. But todays commercial big rigs are set up to shut down after 10 or so minutes of idling. They are that way straight from the factory. And this didn't happen just yesterday, cause I retired in 2003. Company I drove for, if you idled the rig to long, you were gone in no time. And the built in tattle tails told on you. They don't want you wasting fuel! And diesels are diesels no matter whether they are "big rigs" or RVs!!! And some of todays RVs have the same Cummins ISX (500 or 600 hp) as the bigger big rigs have.
