That type of long frame the truck has is meant for flatbed and dry van box and other body who are mounted on the truck frame, but does not accomodate for a hitch so far back behind the rear axle.

When driving up or downhiill or turn this lead to unstable situation.
Those type of trailer addon doesn't belong to the current frame configuration.
