Yesterday I came across a guy who backed his trailer in too far and the axle went off the end of the concrete slab. It's a nasty drop, at least 2 feet straight down, so the trailer was seriously stuck. He had an F-250 and was pulling for all he could, and was not able to budge the trailer. His buddy figured that they just needed more power, so he hooked up his diesel dually to the F-250 to try and pull it out. Well, he hammered the gas, smoked the tires and literally snapped the trailer in half. The entire front tongue section was ripped clear off. The back portion was still hung up on the drop, so he wades in to hook up a chain to that part. Now this guy is from somewhere deep in the south, as he said (in the most hillbilly southern accent you can imagine), "dang! this Yankee water is cold!" Possibly one of the most hilarious comments I've ever heard. Once the chain is fastened around the axle, he hops back in the dually and floors it again. The trailer creaks, then twists and tears as it is ripped against the cement. After he pulled it all out, the axle was twisted, the fender broken, the tire shredded, and the frame was bent. So now, he looks at the two portions of destroyed boat trailer, wondering if maybe using more power wasn't the best solution to free the trailer.
