Today I installed the RigRunner 4005H. This is 5.75 inches wide and fits nicely on the back of my electronics tray. The open door panel on the left is where the power switches are located for toggling this power panel, the main drive power and charger port.
I had previously purchased a RigRunner 4008 but at 9 inches wide, it was too big.
The Anderson Powerpole connectors are quite nice. I purchased the TRIcrimp crimpers and that made attaching the connectors a breeze. The RigRunner came with rentention clips that help secure the connectors to the power panel.
With that installed, the cables are now better organized.
