I haven't been able to find any specific information regarding the stock height of the 4x4 F-250 crew cab. The specs on the Ford website say 81.5" but from what I have seen on the road, that is not accurate. I have a King Ranch with FX4 with a build date of 8/10 coming and trying to figure out if I need to adjust my garage door opening height. I currently have 82.5" from the garage floor to the bottom of the door in open position. Should be able to get another 1.5"-2.5" without major surgery on the garage. Curious if anyone here can confirm what the minimum garage door clearance requirements are.
