I've towed that 9,000 lbs. camper 40,000 miles with the F150s (equipped as mentioned before). Then "up-graded" to the new F250 towing 10,000 miles up and down the same roads in the same weather conditions. Like I said before, I'm not impressed with the new rig.
I often wondered why Skip&shar (a well respected, long time poster here) went from a F150 to a F250, then after 1 year went back to the F150. Well, now I know...
Most guys here have never driven, towed or lived with the F150. They only spew statistics they've either heard or read somewhere. Take from me the guy with real time experience, The F150 ecoboost, max tow, heavy duty payload is a very capable truck.
