New WD Hitch Needed- Reese DC or SC?
We are very seriously considering upgrading to a new trailer, a Jayco 32BHDS. Listed dry tw is ~900lbs, so I am figuring after propane and battery, close to 1200lbs + what is loaded in the trailer, so...

These tube frames are 11 Gauge. That is .12 inches thick. A 1/2 X 13 bolt has .077 threads per inch. That means that the 1/2" self tapping screw will cut 1.5 threads into the frame.
I'm amazed that people even manage to get the bolt torqued to the 50 ft lbs specified in the in the instructions without stripping the threads out of the frame.
There's a good chance that those 1.5 threads will not resist a force that attempts to pull the screws out. A turn at an intersection that places the trailer "above" the tow vehicle (driving down hill) could be enough to do it.
If Reese wasn't having lots of problems from tube frame installs they wouldn't even offer the rivet nuts.
The shoulder on the rivet nut is thin and not much larger than the hole. If you want the DC to sit flat to the frame then you can recess the inside of the DC mount with a drill bit.
I would be more concerned about everything staying together with only 1.5 threads than I would with the shoulder of the rivet nut.
