It looks just like one I built several years ago except I put railroad ties in the ground for the uprights. Everyone that used it said that it was great.
For a mobile bench all you need is a black & decker workmate. Put a 2x6 in the jaws and add bags and a 5 gallon bucket to sit on and shoot.
Pretty much what I use in the local desert. Works fine.[workmate]
Damn nice bench you have there devnull.
