Real world 21BHE tongue weight?

[CWSWine]

I'm sure the transparency of that look up tool is great but you can't beat the towing info GM puts on all (GMC and Chevrolet) of their vehicle's now. Remember the tow/tongue limits are calculated at 10% and 20% for gooseneck. Great truck and trailer combo!!! Happy camping!!!!

You are correct on the 10% but the gooseneck is at 15% not 20%. Here is the link to the info.

The SAE (Society of Automotive Engineers) J2807 States the exceed in GVWR is reason to fail towing test. (Par 5.4)

Finally had a route that took me past a CAT scale, where I spent way too long reweighing at each link on the swaypro. For the purposes of closing the loop on this thread:

5,660 with a little less than 1/3rd a tank of water, two mostly full propane cylinders, and a weekend's worth of stuff loaded (no food/beer).

1,000lb bars on the swaypro:

Tongue Weight:
Link 9/10: 640
Link 11: 700
Unhooked: 760

I used this spreadsheet: https://www.mygrandrv.com/forum/atta...4&d=1543714648
