I sympathize with your delema... A cople of months ago I was struggling with the same questions. While I don't have a slide-in camper, I do have a travel trailer that we tow for a couple weeks once a year. I almost pulled the trigger on a F-250 6.2L, but while I can totally understand the logic behind the bigger is better for towing theory, I couldn't see driving that vehicle day in and day out. I finally decided on the F-150 Ecoboost with the 157" WB and max trailer package and its a much better driving vehicle.

What it all boils down to is what you need and what you need it to do.

Safe diving!
