I'm not to worried about it either. My next truck will most likely be an ecoboost F150 once they have a few years on the new drivetrain to sort out any bugs. For what I do, I've occasionally thought to myself "damn, if I had a little more truck I could pull this or haul this"... but never once have I encountered a situation where my ranger would outshine the F150. Maybe if I was trying to fit between two trees somewhere.... but I don't think I've ever needed to fit between two trees with my ranger that an F150 couldn't do. lol
Lets be honest, the current ranger is outdated. The IFS pussifies it as an off road vehicle, the 4.0L SOHC was once a gem but is now an underpowered heavy boat anchor compared to the competition, and we all know the reputation for the auto transmissions. lol, if Ford could build on the current rangers platform using a better suspension and fit any one of those cool new powertrains they have (300hp 3.7L or I4 and V6 ecoboost options) that would appeal to me.
And who knows, it is Ford after all. They do like to taunt and toy with the market. In a few years we may see another mid-sized pickup or really neat things happen with the half tons.
