I don't remember what Leeann mentioned. Its by Progressive Dynamics. They're here in Michigan... support the home team. The batteries are not paired. I 'think' the coach will supply a little voltage to charge the House when running, but definitely NOT the other way. I only say that, because once or twice when traveling long distances the house battery has seemed to have a little more oomph at our destination than it would otherwise... but we're talking HOURS here, so it can't be anything more than a drip... not even a trickle.
Batteries will recover part of their charge when sitting idle after a period of use, due to internal chemistry. On the other hand, depending on how your motorhome is wired, the Progressive Dynamics unit may be able to sense a running engine and use the engine circuits to trickle charge the coach battery.

am going to get to all this, in detail, as I continue my treatise on motorhome electrical systems.
