thanks guys for your input. plugged it all in to a spreadsheet (to get a logical result).
1 vote four 6 volts(sounds good)
1 vote two group 31(thats gonna cost)
1 vote three group 31 and party till midnite(im in bed by 9)
2 votes one group 27(two guys agreeing, now were getting somewhere)
3 votes two 6 volt(that was one of my choices)
5 votes two 12 volt(my other choice)
so two 12 volt batteries it is. and if this doesnt keep me warm all nite, i have alternative improvements in mind thanks to you guys.
put more stickers on my genny
get a small solar charger/dumptruck assembly
get a larger solar array/without dumptruck
seriously, thanks to all
