I went and read the old thread. I wish we had an answer from a RECEIVER manufacturer. I do know I contacted the receiver manufacturer on our 1999 Mercedes ML320. They clearly said THEIR receiver was rated for a 10" distance from ball to hitch pin. They said I needed to derate the receiver capacity if I used a longer drawbar. They said they thought that was pretty standard in the industry.
Sorry I do not still have the email, it was 14 years ago after all.
I know some think if I use a really long length drawbar I could tow a 10,000# trailer with a Pinto, but I'm not going to try it. To each his own.
One final point. It was said no receiver failures were reported here. Didn't I read a lot about GM receivers bending a year ago or so?
It was more than a year ago. I had one on my 2001 dually. What a cheap piece of tin. I replaced it with a real receiver upon finding cracks in the welds...BTW, that receiver towed a lighter TT than I now have with a standard drawbar and was well under the receiver rating.
Did you notice that REESE makes a 14K, 18" drawbar? They also make receivers. Last I checked, their biggest receiver topped out at 15K That doesn't leave a lot of room for derating. Why would they sell such a item without any disclaimer if it cannot be used at that rating?
According to your derating theory, that 14K drawbar would need either a receiver rated at well over 20K, which doesn't exist, or to be derated to about 8K, which no manufacturer of hitches/drawbars recommends.
Torklift also makes receivers. They stated in that thread that there was NO derating necessary with drawbars using WD up to 16" pin hole to hitch hole, or the same as 18" overall.
