Most Popular Fits Driver and Passenger Side for 2013 Mercedes-Benz M-Class

Will find out. Trying them out today

These worked great on my wife's Yukon. Installation instructions were clear and direct. They held up very well traveling 75 mph down the interstate; No jostling around or coming loose. I loved the additional two mirrors. Having the three total different angles while pulling a trailer was extremely helpful. Would highly recommend this setup.

After reading lots of reviews on several mirrors, I decided to buy the K-Source Universal Towing Mirrors. Oh how I wish my truck could use the ones that slip over the existing mirrors! I was prepared for a fight, based on reviews, and boy did I get one! I truly needed a third hand when figuring out how to attach these. I was bound and determined that I could do this on my own. No mirrors were going to defeat me! I did ask my husband to come look at them. He started to help but I shewed him away. After a lot of words that don’t normally come out of my mouth and a few tears, the first one was on! Then I had to go do it again in the other side! I’m pretty sure the neighbors heard me yelling. But I persisted! Lo and behold, this 67 year old Grammy did it! It was clear they would not stay on by themselves, so I grabbed a couple of bungee cords and wrapped them around the housing and they aren’t going anywhere. I have left them on my truck. No way I’m going thru that every time we return from camping. I will take them off at the end of camping season. Delivery was really fast. I was disappointed that one box was brand new and the other was smashed and taped, an obvious return. I would have been very unhappy if there was a piece missing or if something was wrong since this was my first purchase with etrailer. Overall, the mirrors work, they do not shake and I find I don’t use the truck mirrors now. Very happy with my purchase.

When installing them for the first time on my 2020 Ranger, I had some trouble with them wanting to side off to the outside of the mirror. Eventually I got them to stay, but was worried they would fall off while driving. I got a piece of string and tied them to the truck mirror. I was very pleased while driving ,as they didn't come loose, and the picture did not vibrate much. Even still, I have tied them on every time I use them. Over time I have gotten pretty good at installing them

I went right away to try them on my truck. I have a 24 Denali ultimate 1500 Denali and I have a couple of cameras on my side mirrors. The straps are easy to maneuver around the cameras to avoid issues there. Good snug fit I have not taken it out yet to test these in real road conditions but so far so good.

Worked well and as expected. Still can't see as far behind the camper as I would like on the passenger side. Strap them on tight. They shook very litte but some, not enough to be bothersome. Later,I did find them less expensive elsewhere, oh well. Straping them on is tricky to not cover the cameras underneath the truck mirrors. Truthfully I use the camera on the back of the camper along with these mirrors and get additional views from the Chevy cameras as well. I'm not a truck driver and only pull the camper on occasion so I need all the "eyes" I can get especially driving through Nashville and Atlanta.

The mirrors were extremely easy and the fit is perfect. These look almost like a factory option installation. All lamp and cameras are exposed and not blocked. The individual mirrors are easily adjustable. Great product! Very pleased.

These mirrors helped tremendously when towing my Micro Minnie travel trailer versus stock mirrors on my GMC SIERRA 1500. The extended mirrors enabled to better determine when it was safe to move back into my lane after passing a vehicle and allowed me to see better the vehicles behind trailer. Although there was an occasional slight vibration in the passenger side mirror, it did not disrupt the usability of the mirrors. The towing mirrors took only a minute or two to install and fit perfectly on the stock mirrors. Adjusting them properly takes a little more time and is easier when a second person helps. I am extremely pleased with this purchase!

I tow a 14 foot trailer these mirrors work great, love how easy they are to take them off and put them on very sturdy. The look almost like they came stock. They don’t move or wobble under high speed would definitely recommend them.

No vibration at all. Great for backing up a travel trailer

Recieve my item in a timely manner and it was the correct part great job.

Mirrors fit and look far better than others I had purchased. Easy to put on the truck, compared to others using straps and even then those aren't all that secure. These mirrors once put on properly don't move. So glad to finally get hold of a product that actual works like advertised.

These towing mirrors work as they should, also look fantastic on the pickup, like they have always been there ... ??????

Excellent Product…Easy to Install and the instructions were very easy to understand… These Mirrors fit perfectly on my 2016 Ram 2500 SuperCrew 4x4 Truck
