Roadtrek introduces the RS E-TREK

Since Class B's and small C's are pretty much the only use for the Onan 2800, I doubt any manufacture sees it cost effective to design a gen-set for such a small market.

Getting back to the E-Trek, I want to know how long term idling is going to affect the Sprinter engine, even with the fast idle installed? Well MB warranty cover it? What about the states than have banned idiling for more than 5 min, if air temp is over 32 degrees?
Every thing I read says extended idiling is bad for the new Diesel engines.
There are a lot of questions Roadtrek has not answered, and I would sure want them answered before I purchased an E-Trek.

The idling question has been discussed a bunch on some other boards. It appears MB wants you to run at highway speeds regularly to clean the DPF and EGR systems, so the idea of spending longer periods while boondocking may be out of the question, regardless of what Roadtrek says. Replacing a DPF is not cheap, and neither is an EGR service, so I also think that there needs to be further information on the subject.

I am starting to think that a direct injection gas engine may be a better choice for an E-trek style vehicle.
