Washing your rv in the lake

They should have disabled the backup lights and brake lights before filming this. If you freeze the video when it cuts to the side view, you can clearly see a person sitting in the driver's seat.

My opinion on page 2 and still my opinion. On watching it another time, the brake lights stay on as long as the guy is behind the MH. When he is no longer behind the MH, e.g. opens the side door, the brake lights go off, then, later, they come back on. Coincidence?
