Personally I am going with a UQ for my rig but my friend insists on using her pad to keep weight down so I decided I would make her a SPE. SO far all the designs I have found do not give any sort of schematic for how to lay one of these out. This is only my second DIY project so still need lots of guidance. Anyone willing to share how they made on of these? I am thinking king of a 4x4 but not sure how to go about making one. Just Jeffs instructions were a little unclear to me, granted I have no idea what I am trying to do.
