I bet you need new batteries. The orginal batteries are know to go out in the first year on about half of all new RV's. So if they are orginal chances are they are toast.
Look for several threads on new Batteries on this forum and consider upgrading to Two 12 AGM or Two 6 Volt AGM . I think they are worth the price.

Thanks LWR:
I just replaced the house batteries (2 weeks ago). Went with Interstate (cheap for now) 6V in series. The "alternator not charging trouble" started before I replaced them and continues now. The new 6 volts are doing great so far, though we haven't really tested them yet via boon docking.
