Greetings everyone....we will be traveling north towards Maine in 2 weeks and looking for an efficient but not expensive way to have power/electric when boondocking....our rig (Odyssey Americana) has what I think a relatively small coach capacity battery, it’s a mighty max 12v 35AH. The battery compartment is not exactly large, so I tend to say that we are kind of restricted on how large can a new battery to buy. We are looking for some suggestions on a new battery w more capacity combined with a portable solar panel.....which should give us a few days being self sufficient.....that’s the plan. I have seen some portable and sort of foldable solar panels on Amazon, is 100watts enough? 200? And what battery should we get? Ideally should be only one battery, that would fit in the compartment.....and do we need also an inverter??? Please kindly let us know your recommendations, ideally a solution that will work and will not break our bank. We have only 2 weeks before we travel....thank you all and enjoy the weekend.
