But, in your opinion, am I better off just sucking it up and buying the 2 6v's rather than buying one more matching 12v and dealing with the decreased capacity? And, if I went ahead and converted to a dual 6v system, would it be possible to make it through a weekend (2 nights) without any solar or other power? (Primarily running lights, maybe radio, and lp furnace at night)
Not starting a pos/neg 6 volt but just get another 12v cheaper and will do you just fine . don't have to worry about 1 6 v going bad and leaving you with out power . you can use 12v in many ways . i have 4 Deep cycle 12's .when fishing i use one as a trolling motor battery the system still works with 3 12v . try that with a 6 V .
2 deep cycle 12 v batts should give you close to 210 amp hr.
since you will be mind full of your power usage the 120w solar should be fine also . 12 volt batteries make life simpler . i get an average of five to seven yrs out of my 12's . Can't say as to how long i can go with just battery power as i've never ran out of juice . on my pop up truck camper i could last a week with 2-12's during hunting season using the furnace every night
