actually, Im a 'survivor' type, meaning I always seems to be spending too much time thinking 'what if[' ... like "what if: I go broke and have to live in my motorhome, away from city electricity ? ... do I have a method for a small 12-volt booth in there ?" ... anyway, after some responses, seems like it's not a viable idea, so 'never mind' .. .................................................. ...................... :stoned:
