Should have mentioned the accumulators I have seen were on large engines, not the DDC small engines, big engines such as the Cat 3500 & 3600 series, and the Waukesha engines that make big hp. All are auto start and go to full power within 8-10 seconds. Turbo bearings need lots of oil right now

Wow my memory is coming back. Used to install a fifteen minute mechanical timer in the dash on coaches sometimes. After a hard pull and then parking the engine would idle for up to 15 minutes then shut off while the owners were having dinner.

Cooled the engine and turbo down versus bake the oil in the turbo at the bearing surface.

I've got a five minute shut-down timer. Just push the button and turn the key off. Drives people nuts when they stop to look at the coach and it suddenly quits! Lots of fun.

Larry,

That five minute cool down may be way too long. It really depends on driving conditions just before shut-down.

If you have just pulled a long grade and pull into a scenic pull off at the top, that would be just perfect.

But, if you have pulled into a CG and have idled while checking in, you can shut it down safely the instant you pull into your camp site.

And, if you have driven city streets getting to the CG, you can safely shut it down 3 minutes or so while checking in.

BTW, this is the advice from both Caterpillar and Cummins.

My slide rooms work better when I have the engine on. They pull from the chassis batteries so I idle till they are out and I am level so I always have about 5 mins of idle time on the coach when I stop.

I agree with the other Brett. If I HAD to idle for 5 minutes, I would use fast idle.

Some thought that the extended idle would reduce the engine compartment temps better for sleeping. Takes hours to cool a ton of hot steel.

Many customers asked for engine compartment fans for the same reason.

We didn't notice any extra heat in the bedroom, but then I think the latest we landed was about 6:30 p.m.

Two to three hours sometimes of heat. But we are dry campers and do drive late at night then stop. Especially a m11 setup.

oh in the winter especially in my old coaches the bed was warm as I pulled in to the rest stop at 9 pm for the night and fell into bed. I loved it. Now the closet is over the engine so no heat issues at all. Though I miss i in the winter. It would cool down in about 20 mins but it was still a nice feeling. I love winter camping more than summer.
