the gooseneck and positioned 4 ft. 5 in. from the rear curve in the gooseneck.
The inner deck panels should make contact with the length of the 4 x 4 in. x 5 ft. timber
laid across the gooseneck. This timber should be positioned 1 ft. 4 in. from the rear curve
in the gooseneck.
The ends of the bridge should overhang the end of the trailer by approximately 6 ft. 4
in., and the side overhang of the bridge should be approximately 2-1/2 ft. on each side.
See the sketch below.
