just bought 2 about a month  ago that are rated 20K with a 5K  tongue weight 
and 
they are not that  heavy.  A lot of weight on 4 ea 1/2  inch  bolts...

Cecil,
I used to work on some big cat engines  with 500 K generators attached. They 
weighed 26,000 lbs The first time we went  to lift one with the crane I took a 
look at the lifting eye and called the crane  operator over. It was held on 
by 6 small 3/8 bolts that went striaght down into  the block. Scared me to 
death but we tried it anyway and wouldn't you know we  lifted all 12 of these 
engines with no trouble more than once I might say.   Cat does make some strong 
bolts. 4140  stamped on the head of each of them.  Thats about twice as hard as 
Number 8 bolt.
