I'm in a dry camping scenario where I'd like to leave my marker lights on during the night.  I'm concerned that they may draw down the chassis batteries too far.  I know I can use my "emergency start" switch to temporarily merge the house bank with the chassis in that case, but, meanwhile...  if I'm running my generator, will the coach charge the chassis batteries at some point?

I know on my Newmar there was a bidirectional relay with some logic that would cross-bus the batteries whenever there was a charge source on one side and the other side got low.

Alternatively, would there be any downside to leaving the "emergency start" merge on for a whole week?  If this is not a constant-duty solenoid I imagine that would be bad.  

Thanks guys!
