Ram 1500 Diesel Towing Capacity?

I do hope over the next 8 years of expected ownership and approx. 100k miles of nationwide towing and total mileage in the 180-200k to share the good and bad of this truck with the forum. It will be biased only in that I just sold a 2008 Lariat f150 that did the above numbers with great reliability, but the 5.4 was a thirsty beast indeed. I explored all the options, and for what I do and tow, this truck surfaced as a real opportunity to have a diesel towing experience but not have the 3/4 ton commitment. If I can realize expected towing mileage in the 15mpg range, then even with higher maint cost this is a slam dunk decision. Having self leveling suspension on half ton, if reliable is a no brainer in my mind. The truck has big shoes to fill. Time will tell..
