Cool idea! I think if I were to make a copy of that myself, I'd add some sort of C channel to the end so it can just slide over the step in either orientation (full table or step & table)
That was my original thought process. The clamps were faster, but the bolts and wing nuts would work too and save money. Thanks for watching and for the comments.
Just thought of another way you ""Might"" be able to add another shelf@@creationsbycarson. On the very top take 4 or 6 metal L or corner brackets & screw them to the sides of the very top that sits on the tire & slide in a piece of plywood. Extra shelf.
Once you build the top shelf drill a hole through the wood & into the top folding part & slide the rod/light holder through & that will even keep the shelf from moving as well @SubaruSleepingwithCarson
