I have a 5x8 enclosed trailer. I only use it a couple times a year, basically bringing games to shows. The crappy rings it came with failed this trip and my games were sliding all over the place. Luckily nothing was damaged. I was peeking in all the trailers at the show to get some ideas. Looks like just about everyone is using E Track. I'm looking for some advice on what brands are good, what accessories I'll need, what height to mount them at, etc. One person I talked to said to stay away from the Harbor Freight stuff and he preferred the click in O rings. I'm not looking for anything super fancy because I don't use it often, but I don't want it to be a pin every time either. Thanks!
