.....you ever used? I was planning on getting a very large battery. Actually 2 but they wouldnt be staying in the van together. They will be switched out..on a cart. The reason? i dont want to use a generator or depend on getting electric from my job. Yes I will be job camping. If I got a larger battery Im thinking I can use a solar panel for the one Im not using and just switch. terrible idea? remember Im not too worried about weight because Im not traveling ...yet.
