Again, talk to a rep at etrailer.
This one fits the '20 hybrid. They should know if it will work on the '21.
The extra price for the hybrid model (I have the gas version) includes extra parts necessary for the hybrid. This is for a carbon canister relocation kit.
It is not as "stealth" as the Mopar, but on this particular hitch, Draw-Tite managed to tuck the crossbar quite high, so only the receiver is visible. See the pictures on the above linked site.
Installation is not easy. I found a guy with hitch experience to do it for about $100. He had a lift, and needed his helper for about 10 minutes of the 1 hour (for him) job. It is even more complicated for the hybrid.
