I just installed my CIPA's Pwr/Heat and used them tucked and extended, these mirrors displayed less vibration than my stock small power/heated ones on my 02. My only complaint is when tucked, the bottom of the inside of the P/S mirror is blocked by the door and you can't see it. Thats where I wanted to put my blind spots. Oh, and I don't think the D/S will turn in towards the truck far enough for my wife (she is SHORT!)
