Hopefully the ford will be better than the Eco diesel dodge I have two friends that own Eco diesel each are nearing 100000 miles one have been great the other not so much on maintaining. The 5.0 ford is an overachiever in the 150 with 8000lb load. I don't care to about dyno numbers just been my real world experience. The 5.0 will edge the Eco when pulling 8000 lbs. Mpgs are at about 7.5 to 8 running 75mph. Christopher if towing local under 200 miles this is probably going to be a great rig and empty mpgs should be great. Long trips get old being pushed around by a trailer and lots of transmission shifting. The life of a small diesel is also going to be shortened when being used at 100 percent duty. Load your truck and trailer up and weigh them it will surprise you on what it weighs.
I agree with you, Ford's 5.0L Coyote V8 is an amazing engine. They are getting similar hp/torque ratings to competitors that are having to use .6 - .7 liters more displacement to achieve.
However, you have to rev it to the moon to get the peak hp/tq (5750/4500 respectively).
Comparatively, the 3.0L Powerstroke reaches max torque at 1750 RPM, less than half of it's RPM range.
Some sweet videos:

If you want to race your buddies up the canyon or to drag race then you probably shouldn't look at the baby Powerstroke.
I do like how in the video the diesel rides the wave of torque in the middle of the RPM range VS the 5.0L sits 500 RPM from it's redline the entire climb.
I've towed a 27' enclosed trailer with a 5.7l Tundra and I know that on long pulls, the engine screaming the entire way really gets old and tiresome.
Honestly, the Ecoboost engines kind of give you the best of BOTH worlds but it doesn't come with the MPG benefit the diesel has. My old 3.5l Ecoboost pulled the same trailer and it shocked me how close to a diesel it acted when towing.
Just some thoughts, I love talking this stuff!
