Be aware with a ScanGauge II

When towing a 5th wheel, it's good to know how your vehicle is performing. Your fuel economy may be somewhat low, and it can be difficult to diagnose problems without sufficient information. The ScanGauge II provides the necessary statistics you'll need to quickly troubleshoot anything that may be wrong with your vehicle.

Its built-in fuel savings tool can help you save up to 33 percent in costs, additionally providing real-time data about your vehicle's performance. Its trip computer stores and displays four sets of data at a given time, including fuel economy, maximum coolant temperature and maximum RPM. Digital gauges provide the same information in real-time. The ScanGauge also features a useful scan tool that receives trouble codes from your vehicle, allowing you to quickly and easily discern what might be going wrong.

"The computer itself is outstanding," writes one Camping World customer. "I use it on a Ram 2500 TD and it is far more accurate than the factory gauges … If you are tow[ing] a 5th wheel, it's a must have! It monitors performance factors you should be aware of, especially in varying climate and terrain.
