Bought a travel trailer and needed tow mirrors as the stock mirrors aren't quite large enough nor extend out far enough to adequately see along the side of the trailer. These mirrors however, are great!There are no instructions in the box that explains how to take your door panels off, so find some YouTube videos that show step by step how to do that for your truck and make sure you feel comfortable with the process before you make a purchase. I will say for my truck, it's was easy. Just be patient and take your time. Having a 2nd person to help is a plus.As for the mirrors themselves, they fit perfect. I did drill the 4th hole for added stability. The main mirrors are nice and large. The curved mirrors on the bottom 1/3 are great. They really let you see closer to the ground and have a wider field of view to the lanes next you. Excellent for lane changing in heavy traffic.The mirrors are attached to 2 posts that extend out from the door and are nice and tight and no slop. They are tight and solid. They telescope out about 4 inches for extra vision when towing a trailer.After I installed, I got on the interstate and drove 70mph and had just a tiny bit of vibration. Keep in mind these mirrors are large so there is a big surface that hits the wind, so having inly a tiny bit of vibration is actually really good. I doubt any mirror this size on any vehicle has absolutely no vibration at 70+ mph. I assume installing that 4th bolt post helped make these mirrors more sturdy. So I'd recommend drilling the hole with a metal bit a little larger than the post when you install. Its not required, but it was easy and the spot where you need to drill is easily identifyable on the door (if you have a truck similar to mine).The upper 2/3 of the mirrors are powered, the curved, wide angle mirrors at the bottom are not. I believe these are also heated, but I live in TX so I'd probably never use that capability. I think the mirrors are about 12lbs each.All said and done, I gave these mirrors 5 stars because the fitment is perfect for my truck, nice and sturdy, great field of view, and installation was easy thanks to the YT vid I found that guided me through it.Hope this review helps you in making your decision to purchase.
