Bit of an experiment here, sorry for the crap photo.
I was hoping I could find a way to install an oem accessory rail system to the bedside. Unfortunately, there's a lot of angles in these 1st gen beds.
- It's possible to install just beneath the rails, however it sits a ways back and will be blocked by anything bolted to the bed rails. That's kind of what I was trying to show below.
- It could be installed midway between the top of the bed and the wheel hump. Right between where I have the two below. It needs to be a short section. The section that goes along the cab fits about perfect and can be purchased separately for a lot less.
- The only other method I can find is to install it directly over the wheel hump. This has some benefits, but also drawbacks. Placement of bottom track in photo.
This is the 6.5' kit for the 07-21 Tundra Crewmax.
