A buddy of mine borrowed my truck to haul home a '78 Bronco that was in a lot up in the mountains. He dragged the Bronco up onto the trailer *** first. When driving home, he encountered a downhill traffic jam and when he hit the brakes, the lightened tongue lifted and he jacknifed the trailer....I remember loading a car up backwards on the car trailer. That did not work well. I wasn't aware that too much tongue weight is a problem until it unloads the front end; then it's a problem.
