I used the bottom tracks when transporting two 140 cubic foot welding tanks (one argon, one C-25). Previously I would rent a Silverado or GMC 1500 and there was no possible way to safely secure the tanks. With the utilitracks, it was a piece of cake.
With the cleats it works GREAT. So far I have used it to transport a 55" big screen TV and also to secure my bed full of camping gear. It is really nice to be able to position the cleats where they will work best for your load. I couldn't be happier...works as advertised. :thumbsup:
