I got tired of lugging around 2x6 boards all the time and sometimes leveling them up was a nightmare. Two- and 1/2-body Lynx blocks and pads now fit on everything. Even on very rough terrain (and we've encountered quite a few of those recently) I have enough to lock, use under the hitch, lock and use under jacks. No more wet wood. These pads eliminate extra blocks and are safer in my opinion. I love her.
