Not so much "do to", but I did pull a broken down 18 wheeler out the road that was blocking traffic. Cop and 18 wheeler driver said there was no way it was going to move, but honestly you just got to get it rolling, and it started rolling fairly easy. No sure I broke 2000rpms, but they were pretty shocked, and I was proud of Ole Bruiser. Driver said he had about 15,000 lbs of cargo at the time.
