Does the tablet holder shake a lot when you're driving? I've been looking at those mount and I'm afraid it will either shakes too much when driving, will let the tablet go when the ride is bumpy or if the plastic will break during the winter and the cold weathers.
Just driving the machine on pavement the tablet does shake a little. I've seen vids of other peeps on trails with tablets in holders, they shake alot. The tablet holder circled in 1st photo would slowly drop, so I used a zip tie to keep it in place. The photo with the arrow pointing to zip tie was taken from the underside.
I agree with NMK about using genuine Ram mounts. I have a couple cheap holders that work ok in my van, but for off roading Ram mounts is the only brand to buy.
