I installed a Torklift Ecohitch myself. Took me a little bit of time but the instructions are pretty spot on - the only trickiness I encountered
* Pulling out the bumper from the sides (where plastic tabs hold it in)
* Misplacing the power connection when reinstalling the bumper (this was minor)
* Redoing the waterproof rubber seal along the edge at the end. Take note of how this looks before you begin.
Fit was perfect, looks like they've corrected the early screw slots misalignment.
While it has great clearance and I'm happy with it,
https://www.chevybolt.org/forum/154...hevy-bolt-ev-today/27450-hitch-bike-rack.html has some discussion on why it may not be as good for towing (vs carrying) as the Draw-Tite. The latter is a 1.25" but is rated at 200/2000.
