Towing tire pressure

I'm the same as Eric...
I run 60 front and 70 rear for towing a 9000# TT with 1100#'s of tongue weight.
I have found going too high on tire pressures has caused me handling/wander issues almost like driving on ice when the pressure was 80...but that's just my exprience.
I've towed 10's of thousands of miles with this Ex and she is a rock solid at 60f/70r psi for towing.
I typically do NOT change tire pressures for the winter either...as the temps drop in Indiana for winter...so will the tire pressures "naturally" so I get a softer ride during winter months too.
The Ford recommended door jamb pressures are what you could carry FULL GAWR's with...so anything over 45f/55r psi is for "tuning" purposes only as the E rated tires load ratings at 45/55 would support full rear axle weights listed on the door jamb for stock size tires...
I came upon 60/70 by trial and error experiments while towing and I seemed to like the feeling and stability.
