All problem solving or decision making will go down some "rat holes" and then go back and pick up on another path. It can happen many times and usually gives very good results.

What is way, way, worse is to pick a solution and then try to justify it by anecdotal information or just plain not admit it is just an opinion and not on data.

There just plain is not information to say Sprinters will, or will not, likely, plug up a DPF early in a class b the runs the engine with an engine generator on a regular basis.

You may disagree, but call it an opinion and accept that others may have another opinion, based on the same incomplete information.

From my perch, you seem to have many anecdotal worries that are unsubstantiated, or ever reported.

Magnifying a shadow will scare many people. But it is still a shadow.


Same coin, looked from different side.

Not confirmed fact, but definitely reported. Very detailed information.

Now, how about those detailed MB specs you were going to give us.

How did he use his vans? short distances? did he do a xx mile of highway speed after 500 miles? what kind of fuel he used? who was maintaining his vans? some houses use resident mechanics. is he trained and qualified?

Not trying to say he is lying or misrepresenting or denying he had a problem. You are using his anecdote to justify your worry shadow. That is ok. Just understand that you are not comparing apples to apples. I thought you are talking about underhood generator and idling. or do you want to expand to DPF in general? There are hundreds of youtube video on GM and Ford DPF problem as well. Not trying to justify one fault with the others'. Just trying to grab a hold of the moving shadow.

He still owned 47 vans over 7 years and was running a trucking business with them every day... would love to see the MB specs that say its perfectly great to run a van at idle or fast idle... don't they already mention short trips are bad? Wouldn't sitting still qualify as a very short trip?

I would like to hear real world experience from RV owners but it may be too soon to tell. The flip side... maybe I don't really care and should buy an RV that works in the moment and sell it after a couple of years (3-5). My planned use would be weekends over maybe 6 months of the year, so I doubt I would get 10 years and 100K+ miles out of it anyway. Also, I live in New England so I am not going to be in very remote places so if there is an issue a tow is possible. I might think differently if I were retiring and traveling full time through the US and Europe but right now no.

The question is whether or not the potential problems (noted in owner manuals) are a reason to either limit idling or not idle at all for camping power.

I think the opinion of several forum members here is to limit idling and get out on a highway after idling. That's my opinion anyway. I think you need to size your battery appropriate to your needs so that you need to idle less.

It might help if we're clear on what our opinions are. I think we'll find subtle but not major differences of opinion on this topic.

I now have vast experience with Sprinters. In fact I am looking at 41,500 miles in 16 months with dual alternator but it seems anything I say gets rebutted by the armchair experts here. For now I will just read with amusement with this one little bit of advice. Don't buy a Sprinter with a Nations dual alternator without high idle and forced air cooling when idling.

41.5k. That's impressive. There's a lot of good information floating around in this thread. As far as rebuttals, if there are 2 or more people in the thread, there will be disagreements.

Davydd - do you idle the engine to charge the batteries or do you idle the engine to run the air conditioner? In the past you've indicated that you do neither.

I think you have also recommended the if you idle then you should drive the unit as a good practice.

Info like that is useful to others considering using an alternator for coach power.

davydd's van would be the last one you would expect to have trouble from idling. He drives nearly every day, or two, doesn't run the AC off of the batteries or engine, or have any other reason to have to idle the van for more than a few minutes at a time.

Someone in the heat, using AC off the batteries so the engine has to run maybe 40-50% of the time, if they stay more than a few hours, is the one who is going to have an issue if idling is an issue, not davydd.
