Even if it works as designed, the problem I see is that it is in a fixed position. I like to be able to my grill around so as to compensate for wind conditions or my patio layout during extended stays. Even if those issues are not a concern for you, do remember that the grill itself will eventually wear out or might not suit you in the first place. In those events you are going to have to either hope you can find an exact replacement that will fit the brackets or put up with having the empty brackets on the side of your trailer. JMHO
