I didn’t really want to get into the fray here after reading the links posted. However since in was initially interested in the EcoHitch being a road biker I will. Now I’m not so sure unless proper measure are taken.
(1) I feel I would feel safer with the FULL pad barrier between the stop bar mounts and the aluminum frame as opposed to just 8 tiny nylon washers on each of 8 steel studs. I realize there’s a tiny gap now between the steel hitch and the aluminum frame but I’d still be nervous about no barrier and pass through. May be sufficient but who knows and no way to check on a recurring basis to make sure all is well without an hours long breakdown and pull apart of the rear bumper setup.
(2) As someone mentioned what about the OEM Factory steel studs Tesla has protruding from the aluminum frame/body? According to TorkLift it’s just a very thin coating on the studs that hey says ‘wears away relatively quickly’. I don’t know if there’s any credence to that statement but hopefully someone could tweet Elon/Tesla this issue to make sure afew years down the road we don’t all have some kind of corrosion issues on the bumper end of the vehicle. I haven’t researched the varied steel/aluminum diagram breakdown of the 3 but I know they’re out there.
Just a few of the issues I thought about while reading the ofrementined links and problems.
