Default Roadtrek Etrek video

This video is from Feb 2016, but I don't recall anyone mentioning it - so here is link.
https://youtu.be/LH507_7rSZE

Nice to see Roadtrek open up a bit about their technology.

It is a cool display. Well done on that!

I did not know the engine restarts for idling time limit was EPA regulated. It can be overridden so ........... what's the point?

That Coach Connect thing looks cool too! It was mentioned in a Roadtrek press release in 2014 - http://www.classbforum.com/forums/f9...html#post21216 - so it has taken some time to get it out there.

It's a wonder that we still call it camping!

This was the first I ever heard an anti-idling rule being applied to RVs. I did some searching on this and don't think the EPA idle limits apply to RVs anyway. They are targeted toward heavy trucks and buses. They are written by states not EPA, although EPA provided a model rule for states to adapt.
https://www.epa.gov/sites/production...egulations.pdf

Here is applicability section from the EPA model regulation.


Section B: APPLICABILITY:
This law applies to commercial diesel vehicles which are designed to operate on highways (as defined under 40 CFR 390.5), and to locations where commercial diesel vehicles load or unload (hereinafter referred to as "load/unload locations").

Source: https://www3.epa.gov/smartway/forpar.../420s06001.pdf

That "EPA idling limit" that Yan quotes sounds a lot like the Mercedes Sprinter diesel limit I've heard before.

Edit: of course some cities have idling restrictions on all vehicles.

I saw that display at the La Mesa RV Super B Show before Yan Seiner showed up.

Interesting about the 35 minute limitation Roadtrek puts on the idling alternator. As I mentioned, I knew about the 5 starts but I can program my Advanced RV to run up to 2 hours on each start. Just starting once with your key resets the 5 starts. So I am wondering if available hardware sets that limit. Anyway, if you sat that long and ran through 5 auto starts it is probably time to drive to a service station for fuel anyway. As for idling I have to believe the Sprinter is less polluting than an Onan generator.

Here's my thoughts for the programmed 35 minutes. After that time the alternator loses efficiency and output due to heat. This I know from monitoring my setup with Nations in testing. The Balmar senses the temp and turns amperage output down. I've tried to explain ARV discovered this and changed alternators away from Nations. For all practical purposes the alternator will charge the battery bank in that 35 minute time anyway. However, some I've learned in the heat of the southwest have found, not in idling, but in driving and running the house air conditioner, that the alternator does not keep up. It seems Texans driving around in 110 degree heat find that necessary. That hasn't been my problem as I am not an air conditioner user unless absolutely necessary and drive with the climate 95% or more of the time. I did get caught up in some heat in Shreveport, LA a couple of days ago. From customer feedback, ARV discovered the "death spiral" of battery charging and running your house air conditioner in those conditions and thus the switch to a Delco. It is not something I encountered because I am on the road almost daily in some capacity and a night's use recharges in a half hour and almost always under an hour so you reach full charge and the Balmar shuts the charging down. So you rarely encounter the overheating situation and probably never if not using your house air conditioner while driving.

The ability of monitoring your coach inside remotely was interesting. It wouldn't work with our cat. She goes under the bed in her hidey hole immediately and doesn't come out.

I am kind of impressed with the quality of this video, compared with previous RT efforts. It was informative, not condescending, and not too squirrelly (e.g., identifying the Balmar regulator by name). The demo unit of the electrical systems was well done.

I guess we are starting to see some results from their new overlords. Hope the trend continues.

I seem to remember that video from some time ago, and I think it was mentioned by someone that it was made before the stuff was released and the Coachnet stuff taken out and AGM added. At that time I think it was a Roadtrek, not dealer release of the video, so that might explain the recent release date on this one.

That video could have been made at the LaMesa RV Super B Show around March 18 this year at the University of Phoenix Stadium in Glendale, AZ. I was there to see that display. I'm guessing since it was published in February that LaMesa must have created that display for the show.
