What size battery(ies) will fit?
Is an RV store a good place to purchase battery(ies)?

BF,
As you know, having as large a battery capacity as one either can fit or can afford means one may have battery capacity so large that - all or most of the time - one uses and recharges only the "very top" of their battery capacity. This means that one's battery(ies) will last the longest time possible, all other things being considered.
Staying as shallow as possible on daily battery discharge cycles is a good thing. One can achieve this simultaneous with heavy daily use of battery energy if their overall battery capacity is large. Also in emergency situations (such as extended low sun-light conditions or being otherwise "stranded"), one may thank their lucky stars that their battery capacity was "larger than normally necessary".
IMHO one need only match daily charging capacity (be it solar or generator) to whatever the average daily battery discharge levels are ... NOT match daily charging capacity to around 50% of whatever battery capacity is installed if installed capacity is large.

I think every off grid RV should have 2 batteries (200 AHs typical) 12v or 6v, don't matter, its still 200 AHs w/o getting all techie.
But between limited life span, and hauling dead weight around, batteries (like horses) eat hay. So my advice is don't have more batteries than you need, meaning, have just enuff to keep from discharging more than 50% each day.
Do have a means of charging those batteries in about 2 hrs generator run time each day,.....even if they don't get 100% charged. If you have 300 watts of solar, and can depend on sun every day, the batteries will take care of them selves, you don't have to even think about them.

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
