I just took delivery of a 2021 RDX AWD Advance. We have a bike carrier ($$) that mounts to a 2 inch receiver hitch. We will not be towing anything. I was quoted a very high price for the trailer hitch plus harness. On the Acura website it looks like they sell a hitch only with no ball or harness. I looked at Uhaul but I'm concerned about their installation expertise and whether it would interfere with the foot operated lift gate and/or the exhaust. Can anyone shed any light on this for me? Thanks!!!!
