Dino and Jerry, think I found a good dash mount for tablets. I think the tablets will be prone to bouncing around due to the weight. This mount I am including the link for has a support arm that should make it more stable. Besides the mount you need to mount a good quality suction disc for the foot.

P.S. Jerry, hope you are healing quickly and feeling better! Our best to you!!!
