I am looking for someone else that has a t32 or similar. I have seen only a couple people with them out there, both towing with a 3/4 ton. I am towing with a 2011 f250, short wheel base, 4x4. 6.7l diesel. We now have around 3000 miles this year and am growing more frustrated by the trip. I purchased the Reese Stedi flex 14000# WDH when we bought the camper. I have the coach riding almost perfectly level, when i have around 20 psi in my truck air bags. I do not have much problem with sway, but horrible problem with porpoising. Does not seem to matter how much or how little air is in the bags. matter of fact, more air makes it worse. Also when my razr is in the back is worse too. Hate to think i may be needing a new truck to fix this problem. My GCVW is 21500, which is well below the 23500 GCVW that Ford says is the limit. Also, anybody, TRUTHFULLY, get any better than 8 mpg towing one of these things. Other than that, we absolutely love it when we get to where we are going.
