I have a '21 Ram 2500, that I pull my Delta 292RL with. I recently purchased the Haloview BT 7 rear camera system. None of the monitor mounting options that came with the kit fit my desires. The dash did not have a good place to put the 7" monitor and I did not want to attach it to the wind shield. What I really wanted was to mount it on my rear view mirror, as the mirror is useless when towing. So I designed a 3D printed mounting that is hung on the review mirror. This worked really well on the 2 week trip we just returned from, to Big Bend. I have posted this mount on Thingiverse for free download for those that have 3D printing capabilities. Have a great day!
