Love my 2011
I purchased a 2011 F350 SRW 2WD 6.7 L Diesel supercab with the integrated 5th wheel prep package including the 10000 lb upgrade. The advantage of the 10000 lb kit is slightly higher payload or hitch weight rate. For my trailer (16,000 fully loaded) and occasional towing that I do, the SRW tow rating is sufficient, I get the antisway software, and it fits in my garage.
