I bought the k source snap and zap clip on's and I'm quite happy. None of the other aftermarket mirrors have the full functionality of the OEM mirrors, and these clip ons work quite well, no vibration, you can still fold them in while attached. They are a good value and get the job done.
Is that how much it'd cost to replace your SUV's mirrors with pickup truck mirrors? Thought that the GMTK2 pickup truck mirrors were wider than the GMTK2 suv mirrors?
If so,the K-Source clip-on mirrors would be even more effective when used on the wider pickup truck mirrors.
