Tons of discussion about this topic abounding on the forums. I have towed a similar trailer with both an Ecoboost 150 and now have a 6.2 SD 250. We didn't have any issues with the F-150, but I feel we really did it right with F-250 with the 5th wheel prep pkg. The prep package really makes things easy. I can sum it up with an impression like this: the F-150 seemed to make suggestions to trailer which were mostly granted well. The F-250 shows the trailer who's boss. If you're planning on any long trips I would not suggest a 1/2 ton. Just my "real world" advice, you will find many others might disagree.
