Diesel engines needed a good long warm up time.. Gasoline engines, however, if allowed to idle for too long fouled and ran bad.. They needed to RUN. not idle.
If anything, it was the opposite:
- Diesel engines (particularly old slow turning ones) are so efficient at idle, they tend not to warm up. They are burning so little fuel and pulling in lots of cold air that it takes forever to get up to operating temps (in cold weather they may never). Far better to just pull out and keep the acceleration gentle for the first few minutes till the engine warms up.
- Gas engines (old carburated ones) needed to get warmed up a bit to avoid stalling. Unless you were leaving them sit for hours idling, as soon as you took it out on the freeway towing, any fouling would quickly burn off.
A lot of MHs run the engine longer than they need to but they do need to bring the air system up to pressure. No experience but I have heard that some get pinhole leaks. They will come up to pressure but it takes a lot longer as it has to overcome the slow leak.
5th wheels...We often leave it running until fully unhooked. Sometimes that will take 5 minutes.
But really, other than curiosity, who cares.
