After towing my new boat home last month and having a few tail wagging problem I decided I need to make sure the trailer is set up properly. One of the things I want to do is measure the tongue weight. My question is what it the proper way to do it. I know there are scales out there that you can use but I am not buying a $200 scale to use once and then have it sit in my tool box. I have seen diagrams online that allow you to use a bathroom scale and a lever but I doubt the accuracy of the bathroom scale (my wife says its wrong every time she stands on it). I also could probably tow the the boat somewhere and weigh the truck, then weigh the truck with the boat hooked on and get a number.
What is the right way to do it?
