I know you said that before and I have tested. You're wrong. Park your van. Close up your van. Stick a thermometer inside and one under your van right in the center. Then tell me again what you said.

I'm not concerned about hot weather either. For one, I would never plan a trip where I encounter extreme temperatures and living in the north it is not much of an issue. As for inside, that would...

Greg, You gave a pretty good overview. gerryM51 has said a couple of times that Roadtrek's modular system was more for their design efficiency across models. To me that is build concern first,...

Advanced RV puts in fan ducted air directly on the Nations alternator. Avanti didn't do that nor do I think Roadtrek or anyone else had. BTW, the fan and duct were removed from my B when the Delco...

You can create a lot of redundancy that will never be used. For instance I have never used a spare tire in over 170,000 miles of Class B RV travel. I no longer carry a spare.

If you say so. ;)

I've had both alternators in my B. I think I have a feel for the performance difference and it is significant. By your own chart you were bouncing up and down for an hour below...

The Roadtrek 200ah battery banks are built from 3.2v li-ion cells the same way. They just chose to keep them as separate banks instead of combining them all in one. It could be to do so and be able...

I am not sure "won't change.....for anybody means." ARV does not have those parasitic loads. They don't have an 800ah system requiring turning four banks on and off. They don't have disaster recovery...

I have no idea. I doubt it. As one ARV buyer said to me, I was lucky to buy when I did because they know their costs and margins better. They also have all the work they can or desire to handle it...
