Best 2021 Mercedes-Benz Sprinter 3500 Towing Mirrors

These are Quality Mirrors, very sturdy. Took me about an hour on the first side, (learning curve) but the second side was 1/2 of that. Makes the truck look great and can't believe what a difference they make for field of view. As for function my truck was set up for the turn signal and power mirrors and they work great.

The service from etrailer was great like always. These mirrors are for our 03 Yukon for towing a travel trailer.They are condsiderably larger than the OEM mirrors in the collapsed position, the once extended they are almost twice as long. The only problem I had is the directions are a bit generic and tell you to pry the power window switch panel from the door panel to access the wiring. The picture supplied shows the lock panel being pried off which is correct but the power window is screwed in from the backside so the door panel needs to be removed and then reach behind it to remove the wiring.

Mirrors work exactly as intended, greatly improving rear vision when towing our pontoon behind our 2014 Tacoma. Store nicely in the compartment under the rear seat.

Excellent product. Easy to put on. Took them off, put them in my camper storage. Next trip out, when I put them on, I did not even need to adjust them! The mirrors are slight contour and slight magnification, which makes them easy to see. There is virtually NO vibration during travel. (I have had others that shimmied so bad you could not see a thing.) I flip my driver side mirror in frequently to check my mail box, so it is not very stiff. So I ran a small bungee from the clamp to the grill under my hood. Did this for both sides. My driver side flipped in when traveling at interstate speeds, so I put a second bungee on it. Fixed the problem. Allen bolts at top of clamp are rusting after 2nd use. All in all though, I am very pleased with this product and it is well worth the money spent. It is the only product I could find to properly fit my 2011 Toyota Tacoma, because it clamps on the mirror frame and does not rest on my truck mirrors. Great Product!

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 absolutely love these mirrors! Very easy to install, about 15 minutes per door. Adjustable from inside and no shake. Can't wait to pull the RV with these mirrors instead of the clamp-ons.

I installed these ksource mirrors on my 2006 Chevy Silverado and as advertised the installation was an exact fit. It took approximately 30 minutes per side to install. The mirrors were an exact fit and the wiring was an exact match. I recommend these mirrors for anyone pulling any type RV needing full side views and beyond on either side of the towing unit. Thanks etrailer once again.!!!

We use these mirrors all of the time when we tow. They fit our Ford F150 truck mirrors like a glove. Unfortunately they can loosen up when traveling so you will need to check the screw on each mirror before traveling to your next destination. We have lost 2 of these in the 6 years we have had our camper for that very reason.

This passenger side tow mirror has the same problem that the tow mirror it replaced had. It is extremely difficult to adjust the mirror the right angle to see down the side of my trailer probably. When trying to adjust it, the mirror just pops to a new position. Most times way too far. I finally got it close and just squeezed on the edge that needed to move some more but to over all mirror angle moved then.. After quite a bit of effort I gave up. If I crook my neck and lower my shoulder just right I can see if there is a vehicle back there but thats not good. The driver's side tow mirror adjusts very smoothly and holds position. I recommend you just buy the driver's side mirror and skip this passenger side model.

They are very easy to install and remove when parked for extended periods. Costumer service was very helpful with getting me the correct marrows.

Great product! I use them on all my trailers as well as my travel trailer. This is actually me second set...the first got destroyed by a hit n run and i could not live without them!

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!

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

I have not used them as of yet, but the fit is very good. The quality is very good as well. I was surprised that I could get towing mirrors for my 2001 Toyota Sequoia.

5,000 plus miles and counting. Leave them on even when not towing. No wiggle. Mountings still secure. Aerodynamic and much more attractive than other mounting systems. Pricy but well worth it. Toyota did not even offer towing mirrors for the 1st generation Tundras!!!

Purchased these to tow a rented travel trailer. They attached securely and provided just enough extra width to see down the sides of the trailer. Mine have 1000 miles on them, no issues.

Once modified slightly, these mirrors work great. For our Chevy Express Van, the collar and hole for the cinching nut needed to be adjusted so the threads on the tightening clip don't have a 20-30 degree side stress on them at the nut. Other than that, they're very good mirrors with little or no vibration while driving. The face of the collar had to be beveled and the hole slotted to allow the nut to angle off correctly. The photos show after modification. etrailer has submitted the photos to the manufacturer for consideration. What easy folks to work with at etrailer.com.

Fit perfect !!!!!! Excellent quality.

I had ordered a set of strap on tow mirrors and was dissatisfied with the fit. They were easily returned and I decided I wanted this pair for complete change out. These mirrors are beautiful and large. They extend approximately 23" from the attachment point to the vehicle. It fits in the same vehicle footprint. They look really good and the lower mirror is a wide angle for added view.

As usual etrailer provided great service and prompt shipping. The product appears as described however I have not installed them.

Installation was very easy and secure. On test run there was no vibration angles remain constant for easy rearview examination

The mirrors help me tow our Lance trailer safely. The adjustable mirrors benefited with a touch of dry lubricant on the joint inside the housing. Emily at etrailer was very helpful!

First set had a factory defect. The hole for the tension knob was not threaded. Replacement sent was also a defect, the mirror panel swivel was un-adjustable. Spend the extra money and get the correct OEM ones for your vehicle.

An exact fit for my 2005 Chevy Silverado. But, since my truck came with only a manual mirror I've had to do some custom wiring to mount power mirror and heater switches to my dash.

These towing mirrors were exactly what I wanted. They fit my 2001 GMC Yukon XL perfectly, utilizing the existing hardware for adjustments and defrost. They extend easily (manually) when towing our pontoon boat, and collapse (manually) against the vehicle when going through a car wash. I should have purchased these years ago, instead of waiting until one of the original ones broke!

Love the mirrors, exactly what I needed. ETrailer would get 5 stars if not for a bit of a fit problem. Both sides fail to make contact with the window molding at the top of the triangle (pics). A separation angle begins just above the main body and pulls further away from the window molding to the tip of the triangle. The passenger side is gapped worse 1/4" than the driver side but both will undoubtedly allow water seepage into the door frame. Would hate to have to caulk these things but tightening and shimming with washers has not worked to change angles at top.Thinking over solutions to save this install.

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.

The company was fast and gave lots of updates for shipping. Once i received product my concerns were met. The straps are BARELY long enough to connect around my mirror. Once it is straped properly the tension on straps pulls them right out of the retaining clip. I ordered these because i have a 11 silverado just like what was in the product pictures. Save your money and get something else because theres no way these will make it down the highway they will barely stay on just sitting here. Kinda disappointed because i bout these for our first camping trip this weekend but these will not work. Seems like a good company just crappy product.

Thank you for the easy shopping experience and delivery.

I installed them on my 2018 Silverado. The fit is good and they look like they came with the truck. Not extended the outside edges of the mirrors are 8'-2" and extended they're 8'-10". They enable me to see around and past my enclosed 8'-4" wide trailer. If you've never been inside a door panel before I'd suggest watching a couple of videos prior to starting. I had to drill one hole in the door (original had 3 bolts this has a fourth stud). I'd have given them a 5 star except the glass shakes slightly when they're fully extended and I hope that doesn't get worse.

I love it,
