The standard 3P hitch bar will not cover that range of adjustment therefore he will be shipping an extended hitch bar. Additionally, since the weight of the hitch is cumulative, he has advised me to go with the 1,400 lbs torsion bars.
This feels like preaching to the choir, but here goes:
The willingness to experiment is key (I feel you already know). A stack of scale tickets with notes about loadings is the "friend" one always has available to consult in the future. The weight range of vehicle loadings is generally narrow, and the possible needed adjustments is correspondingly narrow in range. As Robert Cross
writes, once this range is covered, then an annual check shows good to go.
How to adjust the hitch is now known in advance.
I would start with adjusted empty weights for both vehicles. That means full fuel +permanent items + driver aboard the TV (as it will be higher than published shipping weight), and full water + propane + permanent supplies aboard the TT to estalish what will be the lowest weight one would ever see (as it will also be different from A/S literature). And from there, the range of loadings for short or long trips, extra pax, etc.
Eliminating guesswork is more than just a confidence-builder when one has also verified tire loads with/without WD applied (and consequent TV air pressure).
A few links here from a thread on another forum may be of help if one wishes to be painstaking (even if the TV-specific information is different).
