Small Class B and generator.
I have a 17ft class B with no generator. I am looking at a Champion 1500-1200 generator for charging the 2 house batteries. The only things running on house batteries are the lights and a 12v-120 volt...

Another idea, but it isn't cheap, is to perhaps look at a second alternator with a voltage regulator? That will provide you with charging current for the house batteries, and when they are full, will automatically float them. The advantage of this setup is that you get 100+ amps fresh off the crankshaft.
