I tried this out today using a Pocket PC as an MP3 player.
The battery part works as hoped. I used the jumper cable to connect the two outer posts on the isolator and then measured 13.4 volts at the chassis battery which is my chargers float voltage. (my chassis battery was already fully charged)
The stereo in the Chevy sounds much
better than my TV. Roadtrek added two rear speakers on the conversion.
I found that I had to keep the volume low on the Pocket PC for the best quality sound otherwise there was distortion. After a bit of adjusting I had good quality sound.
rv-n-agin - my TV wasn't in the van so I'll try it soon and post the results. I don't think the FM transmitter is very powerful. (I bought a very inexpensive unit). However, I happen to already have an audio extension cable so I'll be able to have the transmitter near the front of the van if necessary.
I could add amplified speakers or get a radio for the 'house' part of the van but I want to use what is there already. Less 'big' stuff, less weight etc.

That's the bonus! I'll keep a look out for a simple relay to accomplish the same thing without having to pop the hood
Ken-o has a switch on the dash of his Coach House B Van which will temporarily engage house batteries and automotive battery for jump starts.
The jumper cable is an easy way to keep your chassis battery charged if your van is not used often (as long as your van is plugged in).
