A few years ago, I built this shooting bench and a camo cover an patio umbrella. It has bracket that slips into the 2" receiver and provides shade and concealment for spending a day of long range shooting.
The bench is three legged with concrete form board (about 13/4" thick) with carpet top. Works really well.
I am in Western Washington, and can meet up most anytime to deliver.
Email me for pictures.
