Towing mirrors
 

Hi,
I have a 06 Frontier CC LE. Has anyone put tow mirrors on. Any help would be greatly appreciated. I just bought a travel trailer, 23.5/8ft. As my truck is now I can't see a thing behind me. I don't really want to pay $400-installed for the nissan mirrors but I will if it means safety. I have researched some of the clipons and the reviews weren't that great.
Any help/suggestions would be welcome.
Thanks for your time.
Lisa.
