Backing the trailer is difficult for some, blind siding into truck stop after dark is tough for all. Most people have a co-pilot that can jump out and help with parking the RV.
I bought a kit from Tadibrothers.com, it came with a monitor that clips onto my rear view mirror, license plate camera for truck and the Birds eye view camera for the rear of the trailer. I chose to upgrade to 125′ wireless version and get grid lines on the trailer camera. The 125’ wireless version on my 28’ FB ATC Toyhauler trailer works great at speeds under 55 mph and intermitted at faster speeds. In hindsight I would have opted for the 225’ wireless kit for the trailer.
Even though I upgraded the kit to wireless there was enough wire to hardwire the truck camera. I did opt to “hardwire” the truck camera and it is flawless! The trailer camera was pretty easy to install as well. The wireless kit comes with RCA type connections which I sealed with electrical tape. I used the power from the clearance lights to power the camera and wireless transmitter. The connections all fit inside the hole I drilled with the rubber grommet supplied with the kit. I did seal all roof penetrations with Dicor 501 after the install was complete.
I feel much more confident pulling my RV trailer solo knowing that I can see behind me! The 125’ wireless version on my 28’ FB ATC all aluminum Toyhauler trailer works great at speeds under 55 mph and intermitted at faster speeds. In hindsight I would have opted for the 225’ wireless kit for my trailer. Your results might vary depending on trailer composition and length.
