A few comments by Edmunds.com from a test of the 5.0 v8 F150. They recommend the V8 because it seems the ecoboost 2.7 does not quite live up to it's claims.

It's an age-old battle royale among full-size pickup trucks. The 2015 Ford F-150 is unique for its use of lightweight yet sturdy aluminum, but it's not prudent to ignore its rivals. The Ram 1500 is also an Edmunds "A"-rated truck , benefitting from a coil spring rear suspension that delivers a more composed ride and the only diesel engine in the class.
We've been unsuccessful at achieving the EPA's estimates of 20 mpg combined (18 city/23 highway) with our 2.7-liter V6-powered long-term F-150. Our lifetime average remains below 17 mpg.
Our few gripes are minor and include the imperfect MyFord Touch infotainment system. The Ram's ride quality is noticeably smoother whether empty or full of cargo, too. Otherwise, it's hard to beat the F-150.

It seems our young Ram Hating IT Troll may be a bit off with his claims as well.
