Dan, years ago, I had a pickup truck with a slightly oversize shell on the back. I built a locker with drawers that held guns in the front, and on the sides there was a 14" shelf that I could attach my press on, and put my RCBS 10-10 scale on.
I had all my brass ready to load when I got to the range, so all I had to do is powder the cases and seat bullets. Neck sizing was easy to accomplish with the press.
One thing for sure, you sure can work up a load easy and verify.
Currently, neighbor and I built our own 400 yd range, then built a shed with AC and heating, loading and shooting benchs inside, we shoot rain or shine.
