@ChasingOurTrunks - Wow, this is a lot to digest...thanks a lot. I will continue my research to figure out what would be the best option for me. I am looking for a mount that can can easily put on and take off for I will not leave it on the MDX. I will imagine I will only install the mount, or if not possible, store the traction boards on the rig when going on a trip. Not during normal daily drives. (MDX - 2009). Yes you are correct I do not want to drill any holes!!
I currently have Tule Cross Bar and OEM Acura roof rails. And I place a Thule cargo box on top when I travel. If there is a mount that I can install to either my Cross Bar or Roof Rail that would be my first choice. On a separate post, I am also looking for a place to mount my Hi-lift Jack.
Thanks again for the helpful feed back above much appreciated.
