First of all, shout out to Nick @ tackform! I can't stress enough how happy I am with this headrest mount for my 4Runner. I've tested this mount with GoPro 6 and 7 (I got early dibs on Hero 7) attached to a Karma Grip and it is flawless! I even mounted my Canon 80D just to test how it can handle heavier loads and it did it without any issue. Nick threw in a free modular arm extension in my order as well and it just opened new possibilities of mounting positions of cameras inside the truck. I will be purchasing the same mount soon so I can mount my Hero 6 and 7 at the same time inside the truck - front and back and I'm getting a lot of the modular extension arm! My brother liked it so much that he'll order as well when his Hero 7 arrives. Thanks, tackform!
