I recently replaced the factory receiver on my 2005 Silverado 2500 with a heavy duty Curt hitch. My new dilemma, I bought a new WD shank for my Reese WD system due to the new receiver being higher (approx 2in higher). I need about a 7in drop, so I bought the Reese WD shank 3344. I slid the new hitch in the receiver, without the trailer hooked up, I have 8in clearance from bottom of hitch to the ground, I have not hooked up the trailer yet. Do I need to worry myself with my ground clearance? I am guessing I need to have the hitch off when I go up my steep driveway now....any thoughts would be greatly appreciated.
