I was thinking of the same thing for my 5th wheel with a the larger High Sierra,
running 1" ground strap down to cross member that is welded to frame which
hold the bumper. I just didn't know what type of bracket I was going to use
to do such so TNXS for the idea on the MT-1 mount.
Once you have it mounted I like to see some pictures, I'm sure so would others
