It is very simple to program the "X" codes that give many additional gauge functions. Programming the "X" codes such as transmission fluid temperature does involve quite a few key strokes but it is very intuitive. If you have any trouble just e mail or call Scan Gauge as their tech support/Customer Service is awesome.
To install you just plug into the OBD port and a couple of small pieces of velcro will secure the display. Probably take you less than 5 minutes start to finish. My first trip with the SG I managed to improve my towing mileage by 9% just by monitoring the real time mpg and trying to keep it slightly higher than my average mpg. kind of fun to do actually.
When I switched to the Class C I just reprogrammed the SG for the 6.8L V-10 and plugged it in. I run with coolant and transmission fluid temperature and real time and average mpg though it is very easy to simply scroll to any of the dozens of other gauge displays. Also remember that the SG is a built in code reader. Pick up and engine diagnostic code and the SG will read it for you on the spot.
I cannot imagine not having a Scan Gauge.
