I love the e-track in my hauler. I bought WAY too much though and will need to get rid of about 40' of it.
Just a word of advice on the e-track accessories, you can get really good deals on them on eBay, however, they are seconds. I bought the high capacity D-rings for my Rhino which was overkill, but that's how I build

When I got them, I realized the D-ring had been welded in with the flat part on the wrong side. The flat part of the D of the ring, should be in the connector. Mine wasn't, and there's no way to fix it. That wasn't mentioned on the eBay ad... BUT, they were overkill in the first place, and I got them for half price, so I'm still happy
I did buy little e-track ends for mine too. They're soft plastic/rubber things that screw down on the ends to save stubbed toes
