We pull 24' enclosed trailer with the race car and equipment that probably weights 11,000# loaded; once in a while a little more. I have a Joe Martin/Sherline Machine hydraulic tongue weight gauge (http://www.sherline.com/scales.htm) that shows between 1,200 and 1,400 pounds of tongue weight when we're loaded.

I've read some of the threads related to towing. It sounds like the "standard" Prevost trailer hitch receiver is fastened to the engine cradle and has a limit of 10,000 (1,000 tongue weight). Is that correct?

I've read reference to a special hitch/receiver that is rated for 20,000#. I suspect that isn't necessarily tied to the engine cradle. Anyone know how big of a retro fit that is? Cost? Who does it?

Make me smart. Help me out. Thanks!
