Leveling an RV usually means one person watching a bubble while another adjusts, and the lets one person handle it alone. The small sensor mounts to the RV one time and sends live leveling readings over Bluetooth to an app on your phone. You can watch the numbers change while you adjust the RV, so you know the moment it reaches level instead of climbing in and out to check. It installs in about a minute, works with any RV and smartphone, and runs on 3 AAA batteries that are expected to last all season. A 1 year warranty backs it.
