Cons: Does not extend far enough to see past a slide in pickup truck camper.
"I am using with a slide in camper on a pickup truck. The camper is wider than the bed of the truck. On the passenger side, the extension mirror is not far enough out to see past the camper. It may work OK for towing."
"They fit great, however, the outside mirrors vibrate like crazy while driving. I can not even see through them. It is not the mount, the mount fits well. It is what ever the mirror itself is mounted on. I think I can fix it with a couple of homemade shims though."
