I'm pondering whether to install a torklift ecohitch in order to carry a couple of bikes on my 2016 refresh MS. I've read the threads about them and it seems like the installation is fairly straightforward. One concern I have is what potential problems this might cause if I choose to trade in the car later on. I've read where Tesla sometimes decreases the trade in value vehicles with aftermarket mods as they must restore the vehicle to factory specs. I'm curious if anybody with a trailer hitch install has any experience with trading the vehicle in to Tesla (rather than a third party) and if there was any impact on trade-in value. Thanks.
