I used to manage a lumber yard in DFW area. Had a guy show up thinking he could put 20’ 2x8’s in the bed of his truck. He was arguing with a couple of the yard guys who wouldn’t load him. I told him he could either pay $50 for a local delivery, go get a trailer, or come inside and get his money back. He left all angry, and shows up an hour later with a 8’ trailer, I asked him how he thought he would be safe with 12’ hanging off the back. He took his sunglasses off and said “I’m going to drop my tailgate and lean them into the bed”. I pointed out that his plan would only work if he lived in a straight line from the exit of our yard. He stood there for a few seconds and said “I really didn’t think 20’ was this long”.
