What's the best way to break my rig while towing?

But how many times do you back up with your trailer.
I did tow my 4 ft wide trailer behind my dually and fact is that I see it in my side mirror only when it is at 45 degree jackknife, but then- even 360 cameras give distorted views, they do help a lot.
Backing up wide body cargo trailer into tight driveway -that was a challenge since cameras will not see that much back and side mirrors show the trailer wall with no distinction to the position.
