I installed a set of CIPA's TTT mirrors on my 2001 Chevy. I got them used. They worked great and installed in less then 30 minutes. I even painted the removable part to match my truck. Our last truck (89 GMC) had west-coast mirrors from a Mack truck with the braces from an older Ford trailering truck - I hate little mirrors on my trucks.
Here is the propaganda from CIPA:
- TTT Telescopic Trailer Tow Mirrors extend up to 4.5″ to give you more visibility and control over your towing load to a total field of view of 48 degrees.
- TTT Mirrors combine aerodynamic styling with outstanding durability.
- Interchangeable covers give you the flexibility to customize and enhance the look of your vehicle.
- Parts fit most popular towing applications
I also put my Chevy Redneck sticker in the rear window… to help with horsepower.
