I am purchasing a Scamp trailer for some extended backcountry camping for a home base. My conundrum is my battery knowledge. It seems a 29 series is my better choice (unless there is a larger one ). I just dont know how to calculate what I can run and how long. I start reading and I feel like I'm trying to reinvent the wheel. Is the a simple calculation or chart or something to gather this info from or is it just learned knowledge???? Any and all knowledgeable info I will be grateful for. Thanks and Happy Camping!
