That's what I was hoping to hear, thanks.
I did a bit of price checking online, and the deal on ebay was the best I came across. I went with the 32 piece kit, 8 5' long e-tracks, 8 D-ring tie downs, 8 web tie downs, and 8 end caps. Not bad for $140 shipped.
I'm planning on running a strip along the floor on each side of the trailer, about 2' off of the walls. Depending on how I like it, I may order some more so I can do a strip along each wall about 3' off of the floor.
So did you screw into the metal cross beams under the floor or just attach it to the wood floor itself?
