If you like your CTD you can keep your CTD. ;)

I don't think anybody is trying to convince others to sell what they have and buy a 7.3. It's just another option and won't be right for everybody but will be right for some. I know I won't be buying one unless it's several years from now.

I absolutely intend on keeping my CTD until death do us part. The point I was trying to make is that 5 mpg (or possibly less towing a large fiver) will get old pretty quickly....

I got 7-9 mpg towing a 12,000# 37' triple slide 5er with my 6.4L Hemi.
With the same trailer, a 2007 5.9L Cummins got 9-11 mpg. The fuel saved by the better mpg the diesel got was about the same as the increased cost of the diesel fuel, so the overall cost was about the same. The diesel did downshift less though, and it was a better "tow rig" overall. I can imagine with the newest crop of diesels approaching and exceeding 1000 lbs-ft of tq that would only be even better.

The only time I got 5 mpg when towing was with my 2001 Dodge 2500 with a 360 cu.in and 4.10s pulling a 33' bumper pull that weighed about 9k. That old Dodge drank unleaded at a rate of between 4 and 7 mpg depending on how hard it was working. To it's credit, it never gave me any trouble even when I worked it very hard pulling in the mountains at about 200# over it's max tow rating and full of payload, likely over my GCWR.
