I also have been in an ecoboost towing a 3oot heavy bumper pull and the thing handled it just fine, albeit with terrible fuel economy. I still prefer the 5.0 as per Pylon's post, It just seems like such a good choice. If the only V8 option was a 6.2 that got 12 mpg maybe the ecoboost would make sense but the economy savings over the 5.0 just don't seem worth it.

That’s interesting. Anecdotally, I have a few friends that have had issues after 125K kms with their 3.5L eco boosts, but I also guarantee they were bagging their trucks pretty good. Alternatively, I have a friend who is on his second or third 3.5L eco boost and he puts a ton of mileage on his trucks and has had zero issues.
I used to be buddies with our fleet manager at my old company and we had a complete mish mash of 60-70 trucks. I actually don’t think we had any 3.5Ls in the fleet, but we had really good luck with 5.0L F150s. We ended up going all GM with our new orders, but only because they offered a trim level that met our needs perfectly. In the gravy days of oil and gas, the company offered every single make of truck to field guys until we had so much trouble with Dodge trucks that we took them off the menu...haha.
