Update: After sometime towing with these mirrors (20k+ miles), and now moved to a F250 with OEM tow mirrors, my recommendation is to not invest in these mirrors. Their view angles and view area is horrible!! I've almost hit other cars several times when they were in my blind spot. I'd recommend trying the OEM Tow mirrors (if their view area is better??), or keep your OEM non-extendable and get tow mirror attachments. I know, those look ugly, but I'd rather have confidence when looking through the mirror.
