AC to DC Converter for APU

This is for all the RV'ers and/or pilot/campers in the group. I'm wondering
if anybody has ever made an "APU" out of an RV type AC to DC power
converter.

I was wondering if something like the RV converters that take 120AC and
convert it to 12DC could be used to hook up to the apu plug of our Aztec. I
can think of several uses that take more amps than what a little battery
charger would put out, plus it would be super portable.

I see that there are several different output amperages available. 30 amps
would probably do everything I'd want. Our cabin heater, fans, and fuel
pump draw a max of 20 amps. If it is even possible (and safe) could it be
used for jump starting the engines? Each starter draws about 15 amps max.

Has this been done? tried? or is it nuts?

Jim
