>>Is is possible to tow with the f150 up the hills and
down?
A horse trailer? IMHO...NO. I used to have a F150 and hauled a WW 2 horse
trailer, and I would always lose lots of power, even going up a slight incline.
I would not use a F 150 to tow a horse trailer, a boat....yes. Raven (in
the hills of the Twin Cities, MN, LOL)
