If you get a response from someone with the exact same truck and trailer, consider yourself lucky. Note....you didn't indicate truck year.
I simply readjusted mine as needed after lifting my trailer. I'm adjusted for maximum clearance at the bed rails and so trailer is as level as possible when towing. If you go off road, you'll be surprised by how fast that clearance at bed rails disappears, but that varies dependent upon how far back the trailer's wheels are.
Perhaps you can get close via tape measure and some calculations.
