That makes me smile. I grew up in Dayton Ohio, neighbor to Vandalia Ohio past home of the annual Grand Masters trap shoot, and the Ohio Masters. Each year thousands of trap shooters would converge on us, and it sounded like machine gun fire for over 4 days as millions of rounds were fired at the same amount of clay birds. Every kid I knew shot trap, skeet, and most of us hunted, so we loved all the action, and used to walk the Grand, just watching, then a lot of us tried our hand.
The only reason I say all of that is I have seen first hand thousands of gun carts, caddies, and pull alongs. That is in the top 5 easily. Great design Swirt, nicely laid out.
