Found the manual.
For what I'm setting up all my napkin math is pretty much dead on. I need a WDH for our TT. Air ride needs to be allow to rise to height before adjusting the hitch drop and needs to be on for what I want to do. When I have the TT on it I need to be in tow mode.
There's a towing adjusted maint sched and lots of other goodies in the manual.
It looks like I did a good job of matching tow vehicle to TT.
And from the forums I've looked at the 2004 model year seems to have fewer issues than some other years. (Ya know how it goes, some years are lemons and some are peaches.)
Looks like I'm heading in the right direction.
