My first thought is that it's not even a truck. The price will likely be increased and it will be unrepairable. You can't drive a car down the street without side mirrors.
You're not just trying to see your blind spot, which becomes considerable with a trailer, but you're trying to be aware of what's behind you.
I don't have a lot of personal experience with trailers, a few thousand miles maybe. But I've never liked clip on side mirrors. They bounce around/vibrate. A camera system that's optically stabilized and patches into existing displays would feel a lot more natural for someone like me with minimal experience.
