bed rail height

When looking at the trailer measure the frame front and rear(determines how level the trailer is). Most dealers have them somewhat level.

Now measure from the ground to the overhang. If that distance is at least 4 inches more than the height of your truck bed rail you may have a chance.

This allows a 2 inch sag of the truck when hitched which should result in about 6 inches of clearance which is about the minimum you should have.

Back to the drawing board? If you only have four inches of clearance when you hitch up (landing gear still engaged), you still only have four inches of clearance when you raise the landing gear. The FW will go down at the same rate as the back of the truck.
