I have the Silverleaf unit. It was pretty easy to setup.
I bought the base unit from RV Upgrades. https://www.rvupgradestore.com/Silve...tors-s/150.htm
Downloaded the software from Silverleaf website. I had an older Sony Viao laptop, fairly small, that I use for the monitor. I bought a laptop mount and put it on the left side of the steering wheel for easy access. I can still see the shift touch pad and the rest of the buttons on the dash. I played with what PDI's I monitor. The most important for me are engine temp, transmission temp, voltage. I then have smaller screens for trip info (distance, fuel consumption, mpg etc).
Attached is my laptop mount setup and a screen shot. I have since changed the way the screen layout but this gives you an idea of what it is capable of.
