Hi All, I've installed the eco-hitch on the model 3 and installed a Tekonsha ZCI 4 pin trailer light. Everything seems in good working order. What ball mount do you guys recommend to keep a trailer as level as possible with the model 3? Typically on a truck or an SUV the mount hangs down lower than the truck to keep the trailer level. The one for the model 3 should rise as we are lower to the ground, but by how much? if you can provide links to what you purchased, i'll go with that as well. thanks!
