Adding a second battery
Hey folks, I am looking at adding a second battery to my travel trailer. My wife and I don't do any boon docking yet, but I want to be able to have additional power should we lose power ...

Second similar 12v battery in parallel is fine for what you are talking about.#1nobby wrote:
Either way...he needs to buy 2 batteries.
Might as well be 6V.
The OP said in his original post -
"I am looking at adding a second battery to my travel trailer".
As long his first battery is in good shape there's no reason he can't simply add a second similar one - no need to replace it with a pair of 6 volt jugs.
No, there is no "need" but the OP would be wiser by just doing that or, choosing two new 12V batteries wired in parallel. Trying to match a used battery with a new one is a fool's errand. The two batteries will never be electrically similar, in that, the original battery has had it's capacity changed by use.
About the solar charging: You can buy from Home Depot, a 100W solar panel and a Grape solar charge controller for under $150 US.
