steering shake

I posted many months ago about a problem I had while towing. This weekend I towed about 5,000 lbs, bumper pull with no load distribution, for about 600 miles. The truck did well except for the steering shake I noticed at 75 mph. The road was smooth, all interstate, but it did go away when traveling about 70 mph. I've had the tires road force balanced, two alignments and it's stock with 20 inch BFG's AT (2012 Laria 4 door, 4x4, diesel). I'm running 65 psi with a dual steering stabilizer from pro comp and all four shocks pro comp as well. Does someone have any ideas or had such a problem? Could it be the casters or anything similar? Thanks for your input.

It took two alignments adjusting the castor angle to rid my truck of the "shopping cart wobbly wheel feel." I still have the crappy OEM FOMOCO/Rancho shocks and stabilizer too at 29700 miles.

Trac bar bushings? Any death wobble after going over a pot hole? It's hard to diagnose but take the steering stabilizer off and have your deeper check it out.
