I am curious to learn if the Curb Alert would work well in the snow. I saw a picture of a rear of a MS and it completely covered the back up camera. Of course, the back end has some weird aerodynamics going on, lol, causing dirt to accumulate there. Just not sure if a front camera or the Curb Alert would run into similar problems.it works great so far I've tested it on boxes of various sizes. For $149 its a no brainer to protect your front valance/bumper. The beeps are crisp. Some youtube videos available of the system working. Its a very simple device but works well. Camera would be better.
