Went out back to just look at everything in the rig, and relevel it - just because. Well, the Ground Control unit will not turn on. It does nothing at all. Check the battery disconnect to make sure that was not an issue. Slides all work, lights work but no joy on the Leveling system. Checked the battery, its good. Did a search here and found/saw that all of the rigs have the one control module in them - mine does. Decided to download the app. When I registered the app my phone slowed down. Now my Phone will not work, my leveling system won't work, and I'm ready to start drinking a beer, or two, maybe three....
