On the question of charging both the coach and the starting battery's. Many coaches will not do that. I just made a jumper out of #10 wire and ran it between the starting and coach battery's. Worked just fine.
I assume you remove/disconnect the jumper when actually camping. If you don't, you'll run down the starting battery with the house battery, and potentially leave yourself stranded.
Arguably a better solution is the nifty little Trik-L-Start (or its bigger sibling, the Amp-L-Start), a simple little 12V-powered float charger that automatically keeps the starting battery charged when the house battery is being charged. It only works in one direction, and is current limited to a modest amperage, and generally a well-thought-out and reliable gizmo that can be installed and then ignored.
