Project in the making but nearly finished. This is a portable shooting bench that hooks into a receiver hitch and it also has the capability to fold up while attached so a person doesn't have to take it off the receiver to travel. There are adjustments for the table (up and down and can swivel but locks down with set screws), the seat (forward, back and swivels) and then the entire frame can also go up and down for leveling or height differences. Solid as a rock, just need to do some finishing touches then things still need to be painted/varnished.
Here are some pics:
