Backup camera and rear park sensors

I ended up getting a camera, cig plug power adapter, monitor and extension cables from Amazon. I mounted my camera on the handle to my camper so it is near the middle of the camper while moving. The extension runs under to camper then on the side of the camper while it is in my truck bed, then into the back door of my truck to my power. I can just hit the cig plug to turn it on and the monitor sits on my dash. I can watch my boat while driving and traffic behind me. All cost was about $80. I use the monitor, cig power plug and extension when I tow my 5th wheel too; I just bought another camera for it. I can switch back and forth. Works great.
