Haha! Yes, that's where this started. I'm planning on getting a simple ball hitch for the Sierra to make things easy. I'm keeping the WDH for the future because the plan is, eventually (this fall?) to upgrade to a much bigger TT. I can do 800lbs tongue weight without a WDH, so unless we go REALLY BIG, I may not even need it then.
I'm not sure what sort of torque I need to adjust the bolt on the WDH shank, nor the tools (I don't think...), nor the time to take it to the shop, so buying a new hitch is what I've got in mind since we're travelling this weekend.
Cool, so I'll get a straight hitch which will give me a rise adjustment, and a 2" drop hitch in case somehow I can't use a measuring tape, figure out which is the right one, and return the other. Boom. Done.
...then learn what I've got to do for the WDH so I don't need to own 15 different hitches
