I believe it was last year that I sunk my truck and travel trailer to the axles in my yard. Good Sam had one of the premiere towing services in my area come out and winch me about 180' to the street. They first sent a standard tow truck which was too light for the job. Then they sent another massive truck used for winching and towing full concrete trucks. It didn't cost me a dime and it was all done within about 90 minutes.
I have no idea what that would have cost me, but I'm sure it wouldn't have been cheap. I was very impressed with the way that Good Sam handled it and that they hired one of the best tow companies around.
