I have 2 ScanGauge II mounted in series on my dash. After having a gauge cluster failure on my MH. It was good to see all the dash info on the ScanGauge II display for rest of 6000 mile trip. Plus the ability to see OBD2 codes and reset them. I also have a Ultra Gauge left over from a car that I had. It displays far less than the ScanGauge II and is not reliable on resetting codes on all vehicles.
We winter in Mesa, AZ. Linear Logic is about 5 miles from our RV park. They will update them for free if you go to their office. Great customer service. My original Scangauge II is 10 years old.
