$$ of hitch on back of 5er

We had a hitch installed on our new FW in 2012 at a professional welder's place. Cost, including fabricating the hitch out of square tubing, reinforcing the I-Beams about six feet forward toward the axles and installing a plug-in for the boat trailer, was about $500. Since I was planning on double towing with this FW, just like I did for 18 years with my old FW, I wanted a very strong and stable hitch and I believe I have gotten it. If you ever plan on double towing, I would suggest that you not go with a bolt on hitch as I don't believe they would be as strong an attachment as welding properly. You buy a $20,000-$30,000 FW, don't go cheap on a hitch, the consequences are not worth it.
