Going diesel? Yes, how much you tow makes an economic story, but just liking the way a diesel tows is worth something to me. I get up to cruise speed, in my case 55-60, set the cruise and enjoy the ride. It very rarely downshifts out of OD even on secondary roads. The torque is amazing and worth it to me even if it doesn't make pure economic sense.
Towing at 1,600 rpm up hills I like much better than 3,000-4,000 with gas.
My 2 cents.

I have a Ford F-150 5.4 2x4, 22FB, 4500#
On the trip we took to Minnesota, we put 1400 miles on it I kept my reciepts. $400+ in fuel costs, not towing all the time took some excursion trips to other lakes etc. Averaged 11.6 mpg. Towed it up around 65 mph using the cruise, came back around the same throttled it myself going up hills. Rarely in OD.
Would like more torque, like Ed said gassers get on the pipe around 3500-4500 rpm, a diesel will do 25 mph in 5th gear, always on the pipe making power....
I like my truck but it lacks torque at highway speeds.

I think you will find that 25mph in 5th gear with a diesel dosen't work very well. The diesel engines in pickup trucks are not very big and most don't make much power until close to 2000rpm. At that rpm (around 2000) they make a LOT more power than a gasser. My Dodge starts making power at around 1500 rpm but the sweet spot is 2000 +.

Not in either of the diesel pickups I've owned. My 09 GMC with Duramax/Allison doesn't even shift to third when in tow/haul mode until around 30 mph- and that's when running empty. The 96 Ford F-250 I had with a PowerStroke and 5 speed manual would have been horrendeously laboring to the engine trying to go 25 mph in fifth (overdrive) gear.

l have pulled my recently sold terry 31g with three different trucks. First truck was chevy 1500 second was 2500 with 6.0 gas then I got a 2500hd with the duramax. Just like it has been said, they cost a lot more to begin with and the payback on that would probably not happen, but the way they tow is awesome. If I want to pass a car going up a hill I can with ease. All three trucks I had pulled the trailer Ok, but the diesel was it. I would not ever think of going back to a gasser. I should be picking up my new jayco 330rlts this week and I can not wait to see how my truck does with it.

Not compared to an 8 liter or some of the OTR trucks. Ford and Chevie are light duty rated diesels. The 6 cyl Cummins is rated as a medium duty diesel. All the big block gassers were from 7 liters to 8.1 liters so I would not call our little diesel pickup trucks as big. They range from 5.9 Cummins to 6.0 and 6.4 Ford and 6.6 Duramax to the big Cummins and now Ford at 6.7 liters. None are in the 8 to 10 liter category.

WOW ........ I sure don't get near the mileage you all get. I average 8 to 9 towing our Designer. We weight in at trailer weight at 14,235 lb towing weight. (Cat Scale) I sure wish I was getting that mileage too.

I love the diesel power. I pull my 5vr and my boat tandem. Usally run 65 to 70 MPH at 1800 to 2000 RPM. My truck loves to run at 2000 RPM. Mileage is what it is. 8 to 10. Its the performance thats nice.
