I am focusing my attention on Ultralite TT's whose dry weight is in the range 3000 lbs to 4000 lbs. with a slide-out.
and
Max Trailer Wt. Recommendations for F-150 5L or Eco/Boost
Lets see if we can give you a answer instead of the usual opinion of what what it can't do nonsense.
1. Either engine will have no problems with a 3k-4k dry weight trailer.
2. Agree with Skip.
The F150 with either engine can handle Fords tow rating for that truck. As any 1/2 ton or a DRW pickup that carries weight in the bed the biggest safety issue is keeping loads on the rear axle under the trucks RAWR/tire load ratings.
