I was just about to post with the same question.
I recently towed a 30' BP race hauler with the tremor (22 f350 6.7 3.55). I thought maybe Im over reacting because Ive always towed this trailer with a 450 or 350drw and its been completely stable even on windy days. The trailer loaded ready to race is 13.8, I weighed it years ago and still have the same setup. Maybe its ok I dont know but if I had to make an evasive maneuver I dont think it has the authority. The squat was bad enough were people were flashing me at night and on the windy day it was all over the freaking place. 15-25mph winds.
Im taking the loaded setup to a trusted RV center to get their advice. Dealer tech told me the suspension on these are a little soft for towing as they are for mall crawling/off roading. Its my partners truck and luckily I still own a dually but it would be nice to be a single truck family.
Like I said this could be me from always towing with a dually and being biased/pampered. However its something I AM NOT comfortable with.
