If your going to do something wrong, do it the right way!!
As much as it bothers me to admit, I have done some pretty stupid things with trailers in my younger days. Things like trailers/loads that far exceed the capabilities of the truck, no trailer brakes, overloaded trailer, things like that. The same things many others do on a daily basis. However, in those circumstances, I was well aware of the problems, and drove accordingly. I didn’t drive any faster than I could control the truck, I left plenty of room around me, and if someone crowded my safety zone, I adjusted my driving accordingly. Just like anyone with a clue would do in similar circumstances.
I have a friend who is constantly buying and selling cars and trucks, many that don’t run. I bet his trailer has more miles on it than most cars. He never maintains it, he never had a brake controller until he bought a truck that came standard with one. Of course, the controller is useless because the wiring is a mess on the trailer. I borrowed his trailer once, years ago, and it was a white knuckle situation the entire time.
