These mounts are designed to work on the head rails, some work on both but others will not because of the wheel wells.
I bought my first Taco in 2015, as I started to go on adventures I noticed how much stuff I was carrying with me, so i wanted something to mount my gear to the bed sides, and free up space on the floor while also keeping my gear in the back of my truck while on the trail.
I started thinking and came up with an idea for some universal mounts that would allow you the option to mount a couple different items depending on the need. Shovel & axe combo, rotopax, water ports, hi-lifts, etc. As I saw more needs I started making more and more stuff.
I am always working on more products so check back to see what i have come up with....
