Ben working on my 6x6 and adding a few things, I'm ventilating the electronic compartment with a small fan and exhaust outlet. Unfortunately with it being so well sealed it gets pretty warm in there, the temps aren't crazy or anything but I figure it wouldn't hurt to get some air in there, it'll be on a switch as well so it's not on constantly.
Also putting together some Blue and Red LED's so when I'm towing something I can hit a switch for the "caution lights" Would cool if they would blink or flash but o-well.
