Turbo- the reason I installed was to see my trailer (tandem waverunners) and works very well. The camera swivels up or down... I haven't swiveled all the way down but I think the rear bumper may block your view of the hitch ball anyway... I have my turned about 1/2 way down to see most of the trailer tongue and what's behind the trailer... I can now see how far the trailer is in the water, etc..
