Back up camera
It's been quite a few months since I installed the camera, and I'm still working out bugs, but essentially I popped off the cover, removed the bulb, and took out the screws holding the light fixture. I had to cut the wires, and strip them. I may have been able to connect the wires and affix the camera to the back of the camper, but I took it a step further, and attached a white waterproof electrical box to the camper, so that the wires came through the back. I made sure that it was sealed well with caulk. I also took care to mark the wires white/black. I think that the two wires that protruded were both white, but I could see into the hole and tell which was black and which was white - I used some white paint to denote the white wire. I had already attached the camera to the plate cover of the waterproof box, with the wires through the cover, so it was a simple matter of attaching male/female ends to all the wires. I put another cover on the waterproof box until Spring, and then plugged the wires into their respective outlets and attached the cover with the camera. Unfortunately, my wire connections were not solid enough, and I've had to replace them, but haven't had it on the road since to make sure it works.
It worked sporadically, and was a great help when in traffic, and also in backing up. I also have a back-up camera - same system - on my van that I use to pull the camper, and when I'm ready to hitch up, I focus it down to the ball and I can generally back right into position and drop the camper onto the ball.
Another project this summer - we've noticed in the past that the inside lights generate a tremendous amount of heat, which is a problem in summer. I switched them with LED for about $35 (no heat). I think that the ones I got on Amazon (others have commented) are not as bright as the original ones, but we haven't tried them under camping conditions, yet. I saved the old bulbs, was careful not to touch them, and I can put some back if we need to. I should also be able to buy a couple brighter LED's for where we need them, if these are a problem.
