Most Popular 7 Inch Display for 2021 GMC Sierra 2500

I had forgotten my account info and called customer service. They were fantastic. Was able to retrieve my business account and complete the order with no other issues. Thank You customer service for being very polite and patient with me.

Very clear image.

THe camera was easy to install, pair and use. However, we got very inconsistent results while traveling. The camera would routinely disconnect from the receiver, search for a connection, reconnect, then disconnect once again. Having a rear camera on which you cannot depend is worse than having no camera at all.

Installation was a snap, works as it should. Installed on 2022 Coachmen Freedom Express 274RKS.

Replaced my Airstream older camera with a newer version about a year ago. The wireless camera behaves better, and the monitor is bigger than the older version. Clarity is very good. Have noticed sometimes (like at night while raining), the color disappears, and it is just black and white. Not sure if an adjustment is needed to correct that.

After discussing my needs, etrailer suggested this unit and it is the perfect solution! It's very well constructed metal, rather than cheap plastic. Setup of the monitor was VERY easy with a step by step guide built in. The camera, on the other hand, did not have very clear instructions, but was easy to install. The camera can be powered by the reverse lights, the running lights or (in my case) powered directly to 12v (I used a 12v power outlet so I can unplug it). I have had people tail gate me in the "no zone" and then pass suddenly. I Don't have towing mirrors. It took a while to find the ideal spot for the monitor (I have a midsize pickup), but it fit perfectly to the left of the interior rear view mirror.

This 2 camera system gives me a full view of the road behind me as well as providing a closeup look at my toad. The backup guide-lines let me drive my 33' Southwind backwards with a trailer without any problem whatsoever.....and I can easily switch between the full-road or close-up modes to check on my trailer/toad when going through dicey road conditions. Very easy to hook up.....wire your power supply line and plug in the rest.

I bought a two camera setup, works great! One camera on the 5th wheel hitch, and one on the rear of the trailer. The camera on the trailer is setup to be on all the time I am driving. It really helps for backing up, but it is even better on the road. You can see cars coming up on the trailer and see if they are going to pass.

The RVS-4CAM works very well and was easy to install both the camera and monitor. The only negative thing I noticed was that because the system is wireless there is sometimes signal loss at highway speeds which can be somewhat annoying. The product quality was outstanding compared to a cheaper no name brand that I had tried earlier for a different vendor. I highly recommend both the camera system and etrailer.

We purchased this camera to help get our rv in and out of a tight storage spot and to see behind the trailer while driving. The tow vehicle is much narrower than the trailer making it impossible to see behind the trailer even with extended side mirrors. This system allowed me to avoid cutting off any vehicles approaching from behind when changing lanes. The display was installed on top of the dash. The camera replaced the built in furion mount on the trailer. Due to short time, the cord was run externally. This kit is meant for a motorized rv, not a trailer. After opening the kit I realized I had to buy an extension cord to run from the display adapter cable to the rear of the tow vehicle. Then the cable could be disconnected at the trailer hitch. When using the system, the display is good, but very narrow field of view, vertically. So I can either see traffic or see the rear of the trailer for backing up. A second camera would seem to be the best solution but not my favorite one. The mic and audio did not work well. I could not hear my wife, but hilariously, I could hear cars at the rear. Might just be me ... I only ever used channel 2 which I thought was the only channel carrying audio. HINT: adjusting the volume was extremely painful until my wife figured out to adjust it on another unused channel. The brightness could not be adjusted making it bright at night. I aimed the display downwards to help. The instructions seem sufficient and are very brief. The system operates like a prototype rather than a finished model. But it does show the camera even with the display on the dash in the hot sun. We used it for the entire 3300 mile trip. It was on the entire time we were driving. I removed the display after returning home with my fingers, no tools. Overall, I am ok with the system. I still think it was the best purchase for me considering the cost of other systems and the wireless connection problems of other systems except perhaps for the most expensive. Note, I read someplace that some states may not allow a display to be on where the driver can see it while driving.

Ez to install—plug and play. Complete wired system—much more dependable than wireless and a lot less fussy to use. I cable tied the wires under a 37’ Class A. Plenty of wire. Used the old wire as fish tape. Old system was 17 years old. Compared to that, this one is high tech but reasonably priced. The flat screen is lightweight and it was EZ to cut the dash to fit. Very happy with this backup camera. Good clarity. In reverse, grid lines appear. It’s good. BTW The pics of the monitor on the box is the old monitor which is huge and heavy compared to this flat screen.

Purchased our back-up camera a year ago and love it. Makes it so easy for trailer hook-ups. Great service.
