KAT,
Some newer versions of te same as mine also crank the APU from the house bank. Some owners in your same situation have added a start battery for the APU - the cheapest, but not smallest you can buy. (Garden tractor batteries are often more expensive than little car batteries.) They usually add a thing called a combiner that will cross the two batteries together only when there is charging voltage available. These devices are vary available at marine suppliers. With that installed the APU start gets charged any time the house bank is getting charged.
My coach came with a battery dedicated to the APU and the APU charges it when it runs, but there is no cross feed and I like it that way.
