its a 2004 and it might be an inch or two high because when the truck blew an airbag I replaced the air suspension with coilover shocks from a Ford Expedition. The truck is level with less than 1/2" difference between the front and back wheels (slightly higher in the back). The top of my receiver tube is 21" from the ground. I assembled the WD hitch using the lowest holes on the shank and the top of the ball is at 22", even though Husky's site says that hitch has a 2-3/8" drop. Looks like I need an additional 4" of drop if the coupler is 17" (accounting for 1" of sag). I'll probably just buy an 8" drop shank and return it if i don't use it.
Thanks for your input, you are literally the first person to give me a ballpark number, and I have called the dealership service dept and left a message with Gulf Stream technical support dept. The dealer tech told me to just bring what I have. I'm sure they just want to sell me a new hitch when this one is too high.
