I would love to find what and where to purchase the tool caddy's in this video, I would email and ask Mr. Barnes but his channel has no email address... Let me know what you can. I have looked at the Robo Cup accessories and nothing like this. He is using Driftmaster rod holders, and yes I checked their site...
Thank You in advance
