Hello hello, I'm doing a battery upgrade for my Dad's 5th wheel, installing 4 new Trojan T-105's to replace the 2 stock ones. I've done this for my trailer already but mine are on the outside.
Being a 5th wheel with the batteries inside the front compartment, I need to know how absolutely important is it that they are in those vented boxes?
I certainly can get two more of those vented boxes for $60 but having a major being ripped off feeling for what's nothing more than molded plastic.
Thanks
