I have a 2002 with the fold in extended factory mirrors that have the small convex in the upper corners. I want to buy a cargo trailer but not sure as to the 105 width or the 96. I had a 7x16 trl and had to rely on the small convex mirrors most of the time. With a wider box it sure appears that the factory extended mirrors aren't going to cut it, anyone know of a different mirror set up or are there accessory mirrors that can be had that are removable when not towing the wide body cargo trailers?
