From what you are describing, I would say no, the mirrors would have to extend several feet perpendicular from your SUV to provide an angled view of what is directly behind your trailer, and to do so they would be in the next lane. To see BEHIND your trailer I would suggest a camera connected to a display screen in the SUV, simular to what motor homes use. Clip on tow mirrors, or extension mirrors are going to give you a view to the side of the trailer, and from that you can see where the back of the trailer is sitting on the road, and the space next to the trailer, but that is about it.
