Ever get anywhere with this? I'm doing some research before I start my f250 truckputer which is what brought me here.
I plan to go as big as I possibly can with the LCD. Possibly even two side by side. I don't care about having to relocate the ac controls or delete some vents. I'd rather use all that beautiful real estate to buy me more resolution. I'll probably go the route you're looking at and get the f650 lower to add the other things I need such as DVD player, USB, Memory card reader, A/C power, D/C power, etc. All switching of accessories beyond that will be handled by the computer -> microcontroller -> relays. This way I can have an infinite amount of switches for future mods without any extra clutter.
