3" receiver on new 2017 SD = stinger is easy now?
Anybody tried it yet? I just found that my new truck has 3" receiver with 20k rating. I think I can buy 3" tubing and make good stinger very cheap.

How much weight are you towing?
There is a big difference between the 3" single tube and the 5-6" span of the super truss, not to mention the supertruss is double the tubing.
I would think with a 20k rating, the hitch connection to the frame is probably pretty close to that of the supertruss though.
Long time since I quit practicing mechanical design, but the weight carrying capacity comes with square of cross section of the beam.
So assuming all tubings are 1/4" walls, the suppertust has 1 of 2.5" tubing and 1 of 2" tubing.
That makes squares 6.25+4=10.25 strength number.
3" square gives me number 9 alone.
Than weak point is going to be receiver alone and hard to beat 3"
I am buying 10k cargo trailer, but even if I pull it behind camper - don't intend to have it loaded.
The stinger will be mostly used with my PWC trailer, that weights 700 lb.
