second battery
I'd like to add another battery to my trailer, however, after giving up room for a sway control and distribution hitch along with the standard electric jack from the manufacturer, there isn't any room...

I have a spot for a 2nd battery in the engine bay of my pickup. I added it there, tieing it in to the trailer charging wire. Also installed a isolating solenoid, so it cant drain the truck battery when we are parked and using it. It doesnt help with boondocking unless the truck is connected, but is great if we stop overnight somewhere. If boondocking and the trailer battery gets low, I would have a charged battery I could swap out
