Big three HD gassers

My new 150 pulls as well or better than my old 250 did and gives a lot better gas milage. I am currently pulling somewhat over 11,000lbs with it regularly now. It definately needs the load distributing hitch more than a 250 but is great other than that and you should probably have one anyway unless you are pulling a 5th wheel. Then you might should consider the max payload package. The 3.5 Ecoboost is stronger than the 6.2 below 5,000 rpm and gives much better fuel economy, especially empty as you plan to be most of the time. You are fortunate to have so many good choices. I do wish that I could have gotten the air suspension on my Ford. I do like Fords and the 6.2 seems to be strong and reliable but it is old technology and does not give great fuel economy, it is already a very low production engine and I expect it to go away altogether very soon.
