Hi everyone, I recently got an EcoHitch installed on my 2016 Model S. For those of you who have had this or a similar hitch installed on your Model S, how do you protect the underside of your vehicle? The L shaped hitch protrudes from the bottom of the car for which the installer had to cut out a little piece on the plastic underside of the vehicle. Now I understand that for 2015 and prior models, TorkLift makes an "undercover" that can be used to cover the hole once you remove the hitch receiver. But there is no such product for 2016 and beyond. Can you please provide suggestions or some perspective on how you keep that underside protected if your car does not have an "undercover" available? Secondly, if I left the hitch receiver always on is that going to be a problem in terms of dust, muck or rust getting into the car from that little opening? Any precautions I need to keep in mind? Thanks in advance.
