I used the 1-4' VT kit and 1-2' VT kit and secured the tracks to my recently constructed cargo deck finished with herculiner. I wanted the conviences of loading gear in any arrangement necessary and the peace of mind of a secure, uncompromised, cargo load. I tried to keep all my gear in 2- pelican 1610 cases, which have wheels and easily slide in and out of the rig. Removing the second rows offers over 72" of comfort once a second deck is added. Overall, I am really happy with the end results. As it has been said- "it's a way, not the only way".....
