Mounting bed bars and RTT

I was wondering if their is any correct way of doing this beside just making it as centered as possible to the eye. Like is eyeballing the best way of centering the tent and bar?

 

Ya know they do make tape measures...

 

YA NO DUHHHH. @CT Yankee
I am asking for tips or any advice besides a tape measure.

 

8.5” from front of bed and 6.667” from back of bed. Torque drivers side to 0.05 KN/m and passenger side to 40ftlb

 

It doesn’t really matter a whole lot. When I had mine I just made sure the majority of it was supported and adjusted as I needed it.

For example I once had it centered on the rack but one of the windows wouldn’t open because it was too close to the cab. I scooted it back enough for the window to clear and that was that.

 

Thank you @erok81
I tried putting it on but it was way too big. I got a huge tent. Sold it today, gunna buy a smaller one.
