SOLAR PANEL

Do you have a 12v tv? 

We have a Renogy 100 watt suitcase system. It keeps our two  six volt golf cart 220 ah batteries charged. We are out for several months at a time . We left home on July 15 and have been on the road for almost a month now. Between driving with the tv recharging and the solar  system, we have no need to hook into the power grid.

When you say 12 volt tv are you talking about television??

also, if I go with 2 golfcart batteries, which ones, and capacity??

Since you seemed to be talking about watching television on battery power I'm pretty sure Leo was asking if your television was 12v.  They used to exist back in the 30s maybe, but are there anything other than 12v trucks/automobiles anymore?

I got a 100W Renogy Solar Suitcase and am very pleased with it so far.  I've only used it for one week on the Outer Banks though.  That's a much different environment than Fall or Winter in the Smoky Mountains, where solar will be pretty much useless.  So think about where you will use yours if you get one.  There are cheaper ways out if you're up on Ohm's Law and a little handy, but the Renogy suitcase is pretty much plug and play.

As for whether to go for 2 x 6v batteries or stick with what you have, being cheap, I'd stick with what you have at least until the first sign of it failing or not keeping up with your needs.  What are you going to do with it otherwise?  With with a boost from solar it will let you camp for days on it's own.  I have 1 12v battery.  I also have a generator though.  I stay at Walmarts fairly often and would never hook up solar or a generator for that unless it's too hot to sleep without air con.  Solar does nothing for you there.

Unless you're planning on days away from shore power you don't need to make a snap decision about this, and even then, if it comes to it, you can charge your pod battery with jumper cables from your TV (tow vehicle).  Wait until you're comfortable with your understanding of the options and you have a better feeling for what you need for your kind of camping.  Some people (almost) always stay at commercial campgrounds with water, electricity, sewer, cable, swimming pools, miniature golf, and all sorts of other stuff and wouldn't have it any other way.  If that's you, solar panels will just waste space and money.
