7500# 3 horse trailer w/ tackroom with 2 horses (3000#) loaded and about 500# of tack, feed, etc. 11000# +/-. I've had more when I removed all of the dividers and helped my brother move. I'm sure I was over the 13000# rated weight of the trailer and the truck - cruised at 80 with power to spare.
Its the 2007 Cummins 5.9L. The 2007.5s now have the 6.7L.
