You say that your hitch is a class IV, but then say it's rated at 12,000 lbs. Those two things don't match. A class IV is rated up to 10,000 while a class V is 12,000. In either case, that's rare for any class C, and would suggest a bit more investigation.
Also keep in mind that the difference between the rig's GVWR and GCWR is 5,950 lbs.
I have seen some Class IV's rated at 12,000lbs, which is why this must have been put on custom by a previous owner. As the previous poster said, this needs more investigation to see if the frame has been beefed up.
Good posts, thanks folks.
