Hit it with some rustoleum truck bed liner and then ill mount it:
I dont know if Renogy had a multi-input charger like that when I was looking, but RedArc(the same people that made the brake controlled I put in my Lexus) did. The issue with RedArc's, and the issue it looks like with this one, is that they can only accept 25 or 32V from solar.Have you seen this? I was thinking it may be a great option for my trailer. I am seriously considering adding a couple panels to the roof, so the battery can always be charged if if the trailer isn't plugged in to shore power. This would just add the ability to charge from the truck while connected (albeit at a pretty low amperage rate).
