I am looking for the slip on style tow mirrors for the few times i will tow something long and tall (26ft cargo/car hauler). My OEM mirrors dont cut it. Dont really want to disassemble the doors if i dont need to. The oem mirrors are a folding flag style that do not extend. I was given some strap on types the dont really work well. None of the manufacturers ive checked say they have a model for the expy despite listing for the F150.
