Alain,

Back in the 1990's I had an incredibly enjoyable project where I was shooting video of 0.2" diameter carbon ball breaking a ceramic jet engine blade spinning at 40,000 rpm using a Kodak camera capable of taking pictures at a rate of 40,000 frames per second. Actually I had a full screen image at 13,600 frames per second with that camera and that was fast enough, so that was my setting. Considering camcorders commonly take pictures at 10 to 100 fps, that particular Kodak camera shoots images amazingly fast. At my setting of 13,600 fps, Kodak's camera takes a picture every 73.5 micro-seconds, certainly capable of capturing an image of the tip of the jet engine blade for every inch it moves and since the blade was 1" wide there was no way I could not clearly see the carbon ball strike the blade. It was just a question of where the ball would strike the blade, on the leading edge or the trailing edge or somewhere in-between.

Since the blade and the disk it was attached to were running in a 4 foot inner diameter, lead brick lined spin pit pulling a significant vacuum (1/40th of an atmosphere) my only option was to set the high-speed camera on a tripod outside the spin pit and use two mirrors set at 45°, one inside the pit next to the spinning blade and one outside the pit next to the camera, to get a clear line-of-sight and to get images of the spinning blade and the falling ball through a transparent porthole in the pit's 1500 lb steel lid.

Using the methodology described above it should be possible to set a camera on a tripod in front of the RV and also to the side and use a mirror set right in front of the RV's front window but set at 45° so that the camera can see 90° around the bend and can get an image of the bathroom with not more reflected in that bathroom mirror than the image in a small 45° angle mirror, probably less than 2" square. If that reflected image were that small in the bathroom mirror (< 2") it may be difficult for us to see it. It is also possible that someone air-brushed the picture to remove the image of the small mirror entirely.
