I absolutely hate the suction cup mounts so I made a dash mount for my Garmin Dezl OTR810. It grips the front edge of the dashboard in my 2022 Freightliner Cascadia. The top and bottom are a snug fit and I used a dab of clear silicon on the front edge to secure it in place so it won't slide off the dashboard. There are 4 screws that secure the normal mounting assembly to the back of the magnetic GPS mount.
