That's good to know about the seats, I'll try to get some before they disappear.
Shawn, I do have the Hellroaring isolator, and I still have some battery issues. I don't think I charge both batteries enough, they run down after a couple of times out. Either that, or my starting battery is getting weak, or both. I will probably replace my starting battery with an Optima starting battery this winter, the other battery is an Optima blue marine Deep Cell
It seems like it works well enough, but I did run both of them flat once this season. I carry one of those jump starter things too, can't be too careful with battery power.
