Raspberry Pi seems the way to go. Haven't messed with it, but seems pretty easy to grasp from what I've read
I haven't ventured into it either but the entry price is very low. An additional benefit from installing a single computer board is that it brings all the interfaces and can double as a networked device. In the future, an owner may leave his laptop/notebook at home and have a wireless keyboard that will bring the same functionality, using the onboard device.
FWIW, I was gifted a touch screen and small desktop system I'll be adding to the RV. It will have the full functionality mentioned above.
