Two things (all IMO of course)... First, one should never use cruise control when towing a trailer - so placing a genie in the front receiver for camping wouldnt be a problem (for those who dont "cruise") while towing. Second, cameras arent the only thing used for front proximity alerts. But either way, they probably can be turned off (as in my '23 F250's case). Now, if one wants to view the front of their TV while driving - would suppose the windshield would work better.
The one we have mounts under the bumper and when not used, doesnt effect the OEM electronic nanies at all. However, do agree if using it to say... place a bike rack w/bikes or genie tray w/genie etc.. when not towing may cause some issues with the nanies. Not towing makes the rear OEM receiver available for just such occassions. Again... just my $.02.
Happy Trails!
