I have a 2015 fully loaded lariat and also had a 2013 fx4.
I have had both v8's in mine and those engines are bullet proof IMO. 2015 is actually pretty darn good on gas. I never had any problems with my 2013 also.
2015/ I do not do trades but i have towed with it before and it is very smooth. Did not tow a massive load or anything but it was very smooth. I guess i am biased but i do find the insides of the fords have the edge on most trucks. lots goodies in the lariat that i find very useful. New fords will never rust also
.
I know everyone has there 2 cents about what kind of truck they drive but lots of my buddies have gm and dodge and they love em. I don't dislike other trucks but i test drove a bunch and i really liked the fords .
also ford pricing is on right now, can get get plat for under 60k :P
