It's a one-day PITA. For a new guy. Looks complicated (on paper) but isn't. One has to know weights and then apply proper leverage through the hitch apparatus. That's it.
Just did an autopsy of an H/A setup, starts on Post #50:
Disk Brake Conversion
Here's a handy quote from Ron Gratz
about working the WDH numbers in the most basic sense (for the default TV, a pickemup or similar):
"A properly sized and adjusted weight distributing hitch will
"transfer" a load equal to approximately 20-25% of the tongue weight to the TT's axles.
A load equal to about 75-80% of the tongue weight will be added to the TV's rear axles."
You'll need (and post):
TV door sticker on:
GAWR, FF & RR
And then a set of scale readings for TV & TT, empty
TV, empty: driver, with full fuel (and anything permanent in truck; toolbox)
TT: empty, but with full propane/fresh water plus permanent equip/supplies.
With manufacturer published numbers, and true
"empty weight" one can know the range to work within. Short of this means frustration. Get the published and empty weights, please.
TW: a separate number is invaluable. Home TW Measurement
Once the numbers are available (a full set thereof, otherwise no go) then the rigging can be dialled in. This involves a trip to a certified scale. Use the Ron Gratz chart as shown in the autopsy above, or copy off the blank from the other thread below. Being able to double-check numbers is key.
After that, a few more adjustments as necessary, and scale tickets to confirm.
With future trips, one will learn -- with an accumulation of certified scale weight tickets (3-pad scale) -- the potential range
of adjustments to work with differing loads (short or long trips, different loadings, etc).

Read a good bit. Don't worry over "debates", the money is on having the proper numbers from which to dial in the rigging. The rest is the usual fun-and-games around here.
Numbers talk. The CAT Scale is your friend. Initial adjustments are great, but experience with the TV-TT rig means finding what works best. It is not just a one-time thing, but a trend.
