If you weren't leaving so soon you could have gotten the square tubes from NJ Tackle, I beleave John said he was going to bring some up next time he comes.
I use the plastic storage bins that I put pvc tubes in, I'll tape them together as well as tape the bottoms,imo there better then milk crates as they have tops so to help keep my gear hidden as well If someone looks in my truck.Allso I don't fill the bins allup with tubes so I can have room in them for leader spools,and my other extra termanel tackle.
U have seen my set up.I like tennis ball containers.A guy who used to be my friend is a teaching pro.when they would change the balls out they tro away cases of containers.a case fits perfectly in a milkrate. u can fill em an stack em.Right now the back of my truck looks like the back of ur truck times ten.
