I prefer the GM IFS over the Ford monobeam front axle.
Prefer GM bed, it's a little bigger, straighter sides, seems more "usable"
This is a generalization, but GM trucks tend to be easier to work on. I'm just talking about the easy stuff that I can do myself; oil changes, brakes, replacing a starter, etc
The thing that I find most appealing about the Ford is driving it. I like the seating position better, the feel of the seat, and the view out the windshield. The GM hood is too high and seat too low. Now this is very subjective and only applies to me.
I prefer the 7.3 in the Ford, not a fan of direct injection in GM. (gas engines)
I'm ready to be swayed one way or the other.........
