"Low Tide" that's what did it. Last year while launching, a guy with a old 27ft cruiser was launching with hi brand new black GMC grew cab dually. I came back from parking our trailer and the wife asked if I could help this guy. He was standing there perplexed because he luanched his boat and couldn't get the trailer out. When I saw how far he had backed in I told him he was probably off the ramp apron and dropped the wheels into the soft mud. I suggested he and his friends try to lift the empty trailer or jack it. Of course he said with this new rig he could just muscle it out with the truck. Well after ramming the trailer, smoking about half the tread off the tires he finally backed up to the bed of the truck and rammed it home. The result was a trailer that now had a trapezoid shape and went sidewas up the ramp. He parked it and went out on his boat!
