I am getting ready to start pulling with my X, and plan on keeping the trailer around 4000lbs UVW that will give a little "breathing room" if you will. I have searched around and around for an OEM hitch and finally found one at my buddys wrecking yard, I am going to go down and pull all the required components next Monday. I have not seen anywhere where you can get the oem hitch new for a while. I work for a outfit that does hitches/5th wheels for RV's and in looking at what is out there aftermarket for out rigs is pathetic. If you can do so, try to find OEM, good luck!
