There have been quite a few threads over the years regarding AC
converters and attempts to run microwaves, or whatever off the
auxillary battery. Overall, the general consensus is, if you want
that type of power get a small Honda generator (i.e. a quiet generator).

Periodically, Dennis, or someone else puts in how the large RVs do it
(series of golf cart batteries.

Okay. Fine.

What I'd like is an autostart generator (but quiet like the Hondas)
that will sense when my auxillary battery is getting low and
automatically start up to recharge it....and then, when it is
charged, shut down. Called it a hybrid generator. :)

Okay, I'm likely dreaming that this small generator would be portable
and self starting (with appropriate signal capability.) It's Friday
somewhere, right? (Well, New Year's Day, at least somewhere....)
