You may be better off adding batteries and a small generator to charge them with. I had 4 batteries and a 1000 watt Honda and it took care of our needs including lights and a TV/DVD combo.
With just the batteries we could go for almost 3 days before needing a recharge. For a week if we were power conserving (coleman lantern instead of lights).
The Hondas are not designed to be used in an enclosed are but will work if you have a fan and vent the exhaust.
I have a 1994 Yamaha 1000 watt generator and a new Honda 2000 Companion. I bought the Honda when I was having some gas tank issues with my old Yamaha. Since I got the Yamaha fixed, I haven't even run the Honda. The new 1000 inverter generators are really nice and they are enough to run my AC (5000 btu) in my camper, charge the batteries and run the computer or DVD player. The new Honda 2000i weighs about the same (maybe a little less) than my old Yamaha 1000. Since I don't have electric jacks on my camper, I don't need any more power than 1000 watts. I don't even need that if I'm not running the AC. I can get by for several days on two fully charged 12 volt batteries since I am using 100% LED lights and the only other significant use of electricity is the heater fan during cold days.
As far as 6 volt vs 12 volt, I'm sure the larger 6 volt batteries will produce more power, but for me I don't use all my 12 volt power so it doesn't pay for me to go to the extreme. Besides, if one of my truck batteries goes bad, (diesel) I am set up so I can use one of my Camper batteries to get me going again. I like redundancy.
