Haven't been on here for awhile.  Now have about 50000 on the clock and I really like the truck, no problems, just regular maintenance.  I have been towing a converted cargo trailer into a toy hauler and all I did was put some air bags on.  Tows great and gets around 15 to 16 mpg while towning.  I am thinking of going to a larger toy hauler about 28 ft, with a hitch weight of about 750 lbs and trailer weight of 7000 plus probably about 1000 lbs of toys and cargo.  Question is, would the truck still tow that properly if I just added a equalizer hitch.  Another question is their a way to tell how many miles I have towed when I have the tow haul mode turned on. Thanks for replys.
