The computer mount is a block of wood shaped to fit int the coin box on the middle switch panel. The power supply, DC adapter, USB hubs, and all that stuff that connects to the computer are insdie the center switch console. I purchased several more OEM switches from a Dodge dealer and have switches on the center switch console to turn off the DC power adapter for the computer, and another switch to activate the solenoid to turn off the LP GAS tank under the truck, and another switch to switch the REEFER/FREEZER from DC to GAS, (it goes to AC atomatiacally when I hook up.) And finally, I have a solenoid operated gate that Sportmobile sent me to open the drain on the grey water tank. Right now that switch is the Sportsmobile OEM behind the drivers seat, but I will also rig an OEM switch in the center switch console to operate that solenoid too. I know I will get major grief from the enviromentalist about this but I do sometimes dump the grey water tank whil under way by just punching the eject button. It's only shower and dishsoap water. We don't run a black water tank, we have two Porata Potties - one very small, and one very large. They are both stored in floor cabinets in the rear.
The computer mounts on a piece of diamond plate attached to the wood block that fits in the coin tray.
