Have been measuring, planning and looking underneath the TH for installation of pingel wheel chocks for 2 motorcycles. Plan is to place the chocks between the front tie downs points so that the straps are pulling the motorcycle forward into the chocks. In some pictures, I have seen the rear wheels on the incline closer to the rear door. Curious how others have done theirs? Up towards the sliding class door and wall using the tie downs there or further back using the center tie downs?
