Have had one on three of the four Cats that I have owned. It is a wonderful product, and prevents any movement at all of the troller. IMO, it is the best lock down on the market. On the MK, installation was fairly simple, but I have never done an install on the MG. The troll tamer design for MG is a little different, but install should still be easy. Unfortunately, on my 2019 Classic, the distance from the bottom of the Ultrex mount is too short to install any of the available tamers for MK, or I would have one on it also.
