3" receiver on new 2017 SD = stinger is easy now?

Unfortunately it is not. In my remodeling carrier I have seen it lot of times, when home-builders tough that 2 pcs of 6" tall headers will make the same what 12" header for garage door.
A year later 1 FOOT sag proved them wrong.

I think I can buy 3" tubing and make good stinger very cheap.

A hollow ball mount - not something it's want when towing heavy.

I don't think the stinger is the only factor. If it is going to be short like mine, I don't think it matters. I think you have to consider the total system which includes the truss and also the hitch.

I think you guys misunderstood the concept behind TL stinger.
It is not a truss. They are 2 separate tubings. The loose bracket is not design to hold anything.
At least that is what I observe on pictures and videos.
So coming back to my calculation, single 3" tubing has about 90 percent of strength of TL stinger.
I even assumed TL stinger has 2.5" tubing all the way, what is not always the case?

Agreed. Comes down to tow weight, stinger length, how much you tow and how much of a safety factor you want vs risk you will accept.

Our 24" long by 2-1/2" stinger has pulled our 7,500 lb car hauler/jeep many miles behind our 2006 F-350 DRW. But, me thinks 24" is about as long as I would go with that setup towing that weight.

If I were to need a 48" stinger towing 7,500 lbs, I would definitely go with the TorkLift SuperHitch set up.

A truss is far superior then just the amount of material used. This makes them much more sufficient and why they are used. Because the two tubes of the super truss are spaced apart, the strength is far superior to just increasing the size of a single tube one size.

Your 3" tube has vertical leverage of 3" while the super truss has a vertical leverage of at least 5" (assuming 2" tubes).

However, on side-to-side loading, you are correct that the 3" tube is comparable to the side loading of the supertruss. But since it is still less than the double tube, why would you think you can get by without the chains. Probably could in most situations, but not in an emergency situation.

Not saying it won't work, but just trying to make sure you have considered things so you have an enjoyable trip.

I think either way, some fitting is required unless you left it full length.

Yeah. The $30 plus 1/2 hr of work to make ordinary beam working as stinger sure beats the expense and labor of fitting those aftermarket stingers.

With the 3" Super Duty hitch, if you are using a TC that has an overhang that requires a 36" or 48" extension to tow a boat with 500# tongue weight, can this now be done without a Torklift super truss extension? This would be great not having to swap out the factory receiver and install the TL receiver and extension.
