If the trailer is taller than the tailgate, it should be no problem. If the trailer is smaller than the tailgate height-wise, than it can be a little tough.

I have the rear view camera and beepers. They are nice.

The biggest issue I imagine with a cap on when towing a trailer would be trying to back up while turning/in a non straight line....essentially seeing through the sides of the cap. I know most caps have large windows on each side, but there will still be blind spots.

As was previously mentioned, this is where using your side mirrors comes in. So, obviously it is doable.

Yes use the side mirrors.
Problem here is you can't see the far corner of the trailer. Trailer blocks your view more than the topper.
