For those of us that like to camp off the grid, we soon discover that one battery isn't going to cut it. The cheapest route is: New battery box to hold to 6V GC2 batteries, two 6V GC2 batteries purchased at an outlet store or golf cart distributor (if you like quality and are willing to pay, buy Trojans from a golf cart shop), disconnect switch to interrupt power while in storage, circuit breaker to handle the draw from the batteries and the charge current in, cable to connect it all. That is the easy part.
The other part of this is how the batteries are going to be charged. Solar is one way, generator powering the onboard converter or stand alone battery charger, or connect shore cord to power converter or charger.
I chose solar since I don't have to move batteries for Winter storage, don't need to lug gas or generator, don't need an outlet. The capitalization cost is evened by the cost of fuel or 120V power. Solar does a better job of maintaining my batteries than I can with multiple 120V charging devices at my disposal. I nearly never park at a campground with 120V power available. YMMV.
