I've got a 2014 with the 5.0 and it seems to be a strong and reliable motor by all accounts I've read. I think all 3 are pretty good but the 5.0 is a slight step above all of them in regards to reliability
The 5.0 is the new version of the 302ci ford standby. Like i said, we have a ‘13 with the 3.5 and the way it pulls our boat is impressive. This could be my last truck purchase ever, so im looking for something i can drive the wheels off of.
