That will get you the right number. Keep in mind your truck will squat a bit though. But the shank you get should be adjustable anyway.

If in doubt get the slightly longer drop shank and you can adjust to suit your trailer hitch height.

Using their process, everything will line up fine until you put the trailer's tongue weight on your tow vehicle. Then your trailer will be nose low by the amount the TV sinks.

Measure the amount of sink and add it to any rise their calculations show, or subtract it from any drop called for.

Then round off to the nearest inch.

And never find the correct one at the store.

One more probably obvious point.......

A drop hitch is also a rise if you just turn it upside down. Don't spend time looking for a rise if you need it.

Numbers without sag:

TRAILER: Ground to bottom of tongue - 18 1/2"
TRUCK: To TOP of receiver: 19 3/8

So according to eTrailer, I need a 1" drop. Mike, you've got a good point that this doesn't take in to account any sag. I thought about that, which is why I posted and asked for thoughts.

If I get, say 1" of sag, then I really need a flat hitch, right? Just making sure I've got all of this straight. My plan is to buy 2 or 3 hitches and see which gets the trailer level/SLIGHTLY nose down.

Subaru, thanks for bringing that up. I read that somewhere, but it is really good info for the noobies to understand.

Amen, bud! Mike, do you agree with my rough calculations? Anything I'm missing?

Your calculations appear correct. Start with a straight hitch. Flipping it over gives you 2" rise.


Once you hitch up, with the full tongue weight of the trailer on your truck, re-measure everything.


Wait a moment...


Isn't this whole thread about a weight distributing hitch? The shank should be adjustable vs. the head in 1" increments.


Or have you decided to go with a simple ball hitch?

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

Aaaaand, of course the local auto parts store doesn't have a flat ball receiver. Yay!

Stop with your injections of reality.

So he has to visit 2 Wal*Marts, a NAPA store and Auto Zone just to get the pieces. Then run out again because the nut is bigger than any wrench on hand.

Been there. Done that. Toooooooo many times.
