I wanted something similar to what you described. The ready-make portable tables didn't give me the stability I was looking for. Ended up building this one. The large wheels allow me to push it around in the yard for longer shooting distances. The wooden rods pull out and make it easy to "wheelbarrow" around.
Do you still have the plans for this?Below is one that I built, it’s extremely steady and stable but will probably fail the movable part for you. I’ve got a tractor with a front end loader so picking it up isn’t an issue for me.
