I gotta disagree with golfpineacres and Bacon. I understand your post. Lowly half tons are plenty capable of towing 10,000 plus pound trailers. Why would the manufactures even rate them to do so if they couldn't. Ford puts their F series pickups through one of the toughest proving grounds on the planet before they even get put in consumer hands. A F 150 super crew with a ecoboost a 145" WB and max tow package is 1,000 lbs less in the weight of trailer it will tow compared to a F 250 crew cab super duty with a 156" WB and 6.2L gas engine. Both with 3.73 rear ends.
I'm not sure what ecoboost powered F 150 the OP is looking at but I will assume it is a super crew 145" WB and max trailer tow package with a GCWR of 17,100. From what I can gather the OP is looking at a 28' BP with a empty weight of 4,200 lbs. They add some accessories and that pushes the empty trailer weight to 4,700 lbs. He/she and three buddies pushing 300 lbs bring 100 lbs of gear totaling 1,600 lbs. They are going for two days so they bring 50 gallons of extra gas and oil for another 350 lbs. They all ride 2013 M1100 turbos ready to ride at 725 lbs. times four is 2900 lbs
The above F 150 is advertised at 6100 lbs, full of gas lets call it 6350 lbs. add trailer, gear, gas and people equal to 9,550 lbs come is at 15,900 lbs GCVW. That's 1,650 lbs under the rated max trailer weight and 1,200 lbs under the rated GCWR. And under what it is designed to do.
Some of the weights I listed are actual and some are exaggerated. Along the way they pick up 1200 lbs of snow, slush and ice. That puts them at the limit of what is advertised but still doable. Add 10 ply tires and heavy duty payload package and your even better.
As far as it losing power at elevation is incorrect. I think the power of the ecoboost will stay the same up to maybe 10,000 + feet. Not many parking areas above that that I know of.
Like GlennRMK said if you havent driven or rode in a EcoBoost towing you'd be surprised. It really does tow like older diesels and holds its own. I have driven 1 ton diesels over 2 million miles and I'm very happy with my EcoBoost.
