After installing the cab lights, and before Dad left for home he asked me to install his Streamlight charger base and lamp in his truck. After looking around, I found a place that was out of the way, easy to get to and secure.
I made a quick video explaining the install and just like the cab lights video, the iphone camera shot a stupid narrow video which took a hard reset to fix. Sorry about that... but you get the gist of it anyway.
Next mods will probably be some cosmetic stuff, exterior lights, and a leveling kit but ultimately it depends on my Dad. I'd love one of these great trucks but for now I have to live vicariously through him.
