My prior '02' GM 2500HD OEM receiver had the pin-box welded "below" the receiver's main 'round' cross tube, and with heavy tongue weights (within OEM specs) the pin-box would flex upward with the WDH engaged....., compromising the consistency of transferred weight.
I believe in '02' the GM 2500 OEM receiver pin box had one additional gusset weldment than the '02' GM 1500 OEM receiver.
My OEM receiver started bending the center mounting surface and flexing the main round cross tube as shown in the pic:
I upgraded to a Putnam XDR Class V that utilized heavy gauge square tube construction and it preformed great for 11 years:
Now, in the case of the Airstream story add in the lateral forces that a Hensley Arrow WDH places against a compromised (suspected) receiver pin box
