Question:
Hi! Im looking at K-Source Universal Towing Mirrors - Clip On - Convex Mirror - Qty 2 Part Number: KS3891-2 which is supposed to fit my 2014 Chevy Silverado 1500. I am towing an 8.5 wide pontoon boat. With the factory mirrors I get a nice view of the front of the boat! Are these wide enough to work with a boat that wide? Thanks! Darryl

Hey Darryl!
Yes, the K-Source Universal Towing Mirrors # KS3891-2 would be a good option for your 2014 Chevy Silverado 1500 and your 8-1/2' wide pontoon boat. Each towing mirror has a 7-3/4" tall x 5-1/8" wide convex mirror face, so it gives you a much wider field of view than your factory mirrors alone.
I can't guarantee you'll be able to see completely down both sides of an 8-1/2' wide boat since that will also depend on how far your factory mirrors stick out and how the boat sits on the trailer, but these should be a noticeable improvement over the nice view of the front of your pontoon you're getting now.
If you tow the boat regularly and want the most visibility possible, I'd actually lean toward the K-Source Custom Extendable Towing Mirrors # KS62147-48G instead. These replace the factory mirrors and telescope outward, which is going to give you considerably more reach for a wide pontoon boat.
Do your current Silverado mirrors have power adjustment and heat?

I used those mirrors on a 2017 gmc Acadia. They fit tight and unlike all the other mirrors I’ve used, even ones that are custom fit, they did not vibrate. I was shocked.

Hey Jerry! Thanks for your prompt response. My apologies for my not so prompt reply. Had some medical issues that took this off my list of things to focus on! I measured my current mirrors. The distance between the outside edges of the mirrors is 7' 8". If I figure at least 4" on each side, I would need 9' 2" edge to edge. Each mirror has to make up half the difference, or 9". So the question is, on my truck, does the mirror extend at least 9" beyond the factory mirror? I didn't see any pictures that answered that for my truck, but I may have just missed it. I agree that the mounted one may be a better option, but given that I only do this twice a year, and the can of worms cracking open a 12 year old door would open, I'm inclined to go the temp route! Again, my apologies for not answering for so long! Darryl

We have a 2016 Tacoma that we used to pull a 8 foot wide camping trailer which is close to 30 feet long. These are considerably better than the stock mirrors. However, I would say they are more in the class of “just better to just good enough” than they are “great or excellent.” Don’t get me wrong – I’m not knocking them and they are far better than just using the stock mirrors but a solution that gives you a wide view would be much better.
