I have a blue sea systems automatic charging relay that connects the deep cycles to charge when the truck is running. I'm not sure what I was thinking, but I ran my inverter cable to the starting battery bank, so I get nervous if I'm on a 34 and have made a few cups of coffee and ran the fridge and tv for a day and end up idling for a few hours to make sure they're topped off.

I've thought about switching to AGM's every summer when I test and replace the underperforming ones. This year I replaced 5, but it was still cheaper than buying 2 quality AGM's.

That was pretty much where my idea started. As I researched things, discovered and learned more it evolved into it's current form. Probably still has a fair amount of evolution yet to come too. That's mainly why I posted here, to get feedback, input and ideas which I can factor into my overall plan. Of course I make a lot of plans, but very few ever get put into motion. So we'll see where this goes. I'm also contemplating buying a trailer or 2 (currently renting one) and maybe buy another tractor. Partly as a spare, partly to expand. But that's a topic for a future thread, if I ever get serious about it.
