Furrion Vision S 3-Camera Wireless RV Backup System with 5-Inch Monitor - Rear Sharkfin & Side Running Light Cameras, Infrared Night Vision, Wide-Angle View, HD Resolution, IP65 Waterproof (FOS05TAEN) - Perfect for RV Safety, Parking Assistance & Night Driving

I purchased this for a small travel trailer that I tow with my midsize pickup truck. I had a rear-view camera from another manufacturer installed when I purchased the trailer, but it had a very narrow view, no side cameras, and no audio. I purchased this set as a replacement and installed it two days before our last camping trip.We went to Winchester Lake State Park in Idaho, but when I put it into my iPhone, I didn't specify that we wanted the campground. So, Apple gave me directions to the day use area. When we got there, the directions were to go up a narrow, single lane road. We came to a gate that said, "authorized vehicles only beyond this point," so my wife and I prepared to backup about 1/4 mile. However, one of the locals told us that if we went through the gate another 1/4 mile there was a turnaround we could use to make getting out easier. We took the local's word for it so we went through the gate to the end of the road. The local was partly correct. There was a spot to turn around...if we didn't have the trailer, but not nearly enough room to turn around, even if we tried a15-point turn. So, now we had to back up 1/2 a mile. I turned the "guide" lines on so I could judge how far my wife was, turned the screen brightness up, and put the audio on medium high. We then backed the truck and trailer up at a walking pace, past onlookers, with a hillside on the passenger side, and a drop off into the lake on the other. My wife gave me excellent directions that I could clearly hear from about 50 feet away from the camera.When we got to the entrance, she was able to guide me into a spot where I could slip past the guard rail and back onto the highway to the campground. I KNOW that if we had to rely on our other camera system, it would not have ended with hugs and cheers.The good:The rear camera has a wide field of view is fantastic. It isn't a fish-eye lens so it doesn't distort, but it has a view that covers both lanes left and right from the camera. It has guide lines to help you park it and let you know when you're close to an object. The microphone has good sound and picks up voices from far away.The drivers side camera is nice because it lets you keep an eye on your blind spot.The passenger side camera is nice if you have to pass someone or if for some reason you find yourself in the left lane and have to move over. I don't use the passenger side camera as much because my trailer tires are speed rated at 65mph.The bad:For some reason my driver side camera tends to overpower the other cameras. I have to unplug the monitor then plug it back in to reset it so I can select which camera I want to view on monitor.The indifferent:I purchased the 5-inch model. After using it I would go with the 7-inch model just because it it is bigger. They have the same controls and I don't have a problem with the quality of the monitor, it's just not as easy to see cars that are 60-feet or more behind the trailer because they appear so small on the monitor. One good thing about the 5-inch monitor is since I drive a midsize truck and have limited window and dash space, I don't have a larger 7-inch monitor obstructing my view. That's something to think about in states that enforce obstructed view laws that include phones, GPS units, and things hanging from the mirror. The 5-inch monitor sits on my dash and I can see clearly over the top of it, it does not obstruct my view at all.Installation:Installation was easy. Since I bought it as a kit, the cameras were already synchronized to the monitor, I didn't have to do anything there. Wiring was relatively easy, there are 4 wires on the side cameras, 2 on the rear. My trailer only has 2 wires on the side, so I bonded the three "control" wires on the camera together and attached them to power, then I hooked the black to ground. It works perfectly (the manual doesn't say to do that, but the wiring diagram does show +12 volts on the three control lines and ground on the "ground" line.) It would have been nice if the kit included wire nuts or other connectors, but those are cheap at your local hardware store. Finally, the kit does come with rubber gaskets for each lamp, but I still used RTV to make sure I had a good seal. My RV has aluminum siding, and I didn't want water to slip past any spot on the camera that wasn't firmly pressed against the side of the RV.All in all, it took me about 90 minutes to remove the old camera and side marker lights, install the new vehicle monitoring system, and check to make sure everything was working. That included voltage checks, stripping a couple of wires, and working on the ladder.Would I recommend it?YES!If you have a smaller SUV or midsize pickup with limited window or dash space, the kit with the 5-inch monitor is perfect. If you have a full size pickup or large RV (Tahoe, Expedition, or larger), or if you need a bigger monitor, go for the 7-inch screen. In either case, this system is a bargain compared to the cost of a divorce (or camping with a spouse that won't talk to you)!
