My similar trailer with off road package is parked leveled in driveway. From ground to bottom lip in front of coupler is 14-7/8". I estimate the top of ball height would be 17" to fit in the coupler with the trailer still level.
I have to jack tongue up a bit to get it high enough to make it over the ball, then when I lower it till all the weight is on the ball, it obviously sinks some until I close the latch on the ball, then jack it back up again to take off enough tension to put the WDH trunnion friction bars in place on their brackets attached to the trailer frame. Then crank up the tongue jack until it is fully raised and all weight is on WDH.
