So an update... I was originally waiting on 4th gen ram electronics to release their kit which interfaced the factory "auxiliary buttons". Unfortunately, I would like to get a power solution squared away and they seem to be taking a while.
I looked at the sPOD system, the switchpro system, and several others (including some DIY options). I ultimately decided to go with the sPOD Bantam. It's solid state, has 8x circuits that are each rated for 30 amps, and the control panel is not too large. I opted for the "HD" control panel vs the touchscreen, as all reports indicate the touch screen is difficult to use if your bouncing around, and I just dont like that many screens in my face at night.
It arrives tomorrow, so I will begin to figure out mounting solutions for the control panel and the "fuse box" unit. They connect with a single cat5 cable, so routing through the firewall should be easy using the clutch block off plate that is left open on my automatic truck.
After getting this squared away, next steps will be lighting, my HAM radio, and a bed cap.
