I ended up having to add a ground wire to the Badlands wireless box to get it to work with the 3500. You can also unplug and use the factory corded remote in case the wireless messes up. Also adding some pics of how I did my battery maintainer, 4 Gallon tub mod, and dash switch and volts gauge.
Got first service done, and some pics from July 5 at Bolivar Peninsula. Valves were in spec, no adjustment needed. Rotella T6 5w40, Honda filter and plug, Supertech Synthetic 75w140 for the diffs.
