Lots of 12 volt items listed here.....
I have not tried any of these and have no $$ interest....so don't beat up on me...saying these are dumb, inefficient, etc. These seem to be primarily for OTR truckers, but some are labeled for RV: ...

some of the 12v "trucker" items work well and can last for a long time.
as for efficiency, from a power consumption standpoint, its more efficient running ANY 12vdc component directly from the batteries than it is running a 120vdc component thru an inverter.. the larger the power draw of the component thru the inverter, the inefficiency increases exponentially..
when a generator, shore power or other charging source is readily available, inefficiency doesnt matter as much.
