7. The height of the hitch and the pin box should be adjusted so the trailer is approximately level as it is towed. Allow approximately 6 inches clearance between the top of the pickup walls and the underside of the front of the trailer for pitch and roll of the trailer. (See Fig. 22). For off road use allow more clearance between pickup walls and trailer.
Loosely assemble the four anchor bushings, less the anchor tee pins and handles, to the base arches using the 1” nuts (Figure 5). Loosely assemble the two base arches to the center section using 5/8-11 hex head bolts and lock washers (Figure 6).
NOTE A : Hole positions used in assembly will need to be chosen based on the head height measurements taken previously. Choose calculated height closest to one of the following height dimensions: 14-1/2”(top holes), 15-3/4”(2nd holes down), 17”(3rd holes down), ...
I've had that happen only once but hasn't done it again since the first time out.I have the factory hitch.
Came fully assembled, and the height was exactly what I needed.
Matched what I had on my Y2K.....
I'm happy with most things, but hooking up / releasing, the locking system is very senstitive. It keeps wanting to LOCK.... Trips too easily.
I park in my final location, unlock the jaw(s), get in truck, put it into drive, and the vibration caused by placing it in drive (a little body jerk, nothing out of normal), will trip the locking system.
That's an idea...I've had that happen only once but hasn't done it again since the first time out.
If I'm on fairly level ground I toss mine into neutral let off the brakes, which usually takes the stress off of the lock and then just hit the parking brake.
Pull the handle the handle, hop back in, put in D pop the E-brake and pull out. No "re-locking" so far for no reason.
