Diesel class A idling for a looooong time

I have been driving a 40' diesel class A for about 14 years, and during that time I have heard and read many rants and complaints about diesel owners idling for long times while sitting in the campground, usually prior to departing. I have to say, I have never witnessed this and personally do not practice it either. To get ready to leave a campsite, I run my rig for about 5 minutes to air it up, and warm up the engine. In my opinion, nothing more is required prior to departing.




This morning it happened. We are staying at a resort campground with concrete road and sites that are about 80' long. This morning I was outside taking the pups for a walk, and noticed this rig across the street was idling. The owner was outside, apparently getting ready to leave. As I watched (and while the coach was running) he made at least 10 trips back and forth from inside the motorhome to the pickup truck, getting it hooked up and ready to leave. When I say at least 10 trips, I'm not making it up. There were at least 8 trips to hookup and check out the operation of his lights. Several more to insure the truck was hooked up properly, at least two trips around the coach to check that all was well, etc. I started timing this drama after the coach reached full pressure and it was over half hour, so about 40 minutes sitting, idling. As an owner of a diesel motorhome, I can assure you that virtually everything he did could have been accomplished with the motor OFF! I have no problem with being safe, and careful, just do it with consideration for others.

When he finally finished, and prior to getting into his coach to leave, he looked over at me sitting on my picnic table and walked across the street toward me. He started by saying, "guess you never realize how long it takes to get these things ready!!". I responded, "Yes, especially while your motorhome is idling the whole time, and bothering everyone around you.". He asked if it bothered me, and I responded yes, particularly when it's not necessary. It is rude and inconsiderate of everyone around him. He shrugged his shoulders, and responded, "no it doesn't", before turning and walking away.

I guess it's true, you can't fix stupid. On behalf of polite diesel drivers, my apologies to all those who have experienced this in your travels. And if you happen to come across a Foretravel U320, #17237, Be ready to have your morning sleep disturbed.

    By the way the proper way when starting a cold diesel is right after oil preshure comes up to bump it up to fast idle. On low idle it isn't burning all the diesel and it can wash down your cylinder walls causing more wear and contamination of the oil. The fast idle creates enough boost to increase combustion temps and get a full burn of the fuel.

    Ok I’m going to jump out there and show my ignorance. Are you being sarcastic or should I actually warm up my truck on high idle? 2001 power stroke, I do have a high idle setting but don’t use it much.

    He is ccorrect. A diesel will also warm up faster at high idle.
  • Reminds me of the time when Amy and I were camping at a campground on the outer banks and a big diesel pusher next to us idled his engine all night and the exhaust pipe was pointed at our camper.

    I wanted to go over and stuff something in it. being diesel probably would have done no good but if it was a gasser, I would have ended their stay with the motor running.

    A potato in the tailpipe does the job nicely. Been there and did it before. Take a broom and shove it up real far so no one can figure out why the motor won't run....

    Woke up in the AM and the camper stunk like diesel exhaust.

    Why I like disbursed camping.... No neighbors.
  • I have drive Super duties since 1999 & owned a class 8 tractor. The diesel needs to idle when shutting down to allow the turbo to cool and when starting & warm & build air pressure for the brakes.
  • We work it as a team, Barb gets the interior ready, and brings the slide in.
    I hook up the jeep, and bring in all the hoses unhook/stow the power cord, climb in, start the cummins, raise the jacks. By the time the jacks are up, I have check all the lights, done my walk around.

    Push the big yellow button, and go.

  • .....and then when they do finally leave they lay into their air horn for a "friendly" 30 seconds to say good-bye to everyone in the campground....:M
