I started noticing this. My buddy has an ext cab 94 f150 4x4 and mine is a 94 reg cab 4x4. My truck is significantly taller. Both trucks have stock suspension. And every other ext cab of the 92-96 fseries i noticed this.

 

Actually mine and my bros are just the opposite. Mine's a little higher than his is.

 

Are they the same GVW? my 250 x-cab has the camper pakage and heavy suspension pakage and sits 2" taller than most of the other 1992-1997 f-250/350's in town. its also his the springs are saging on his x-cab's
