I have a version of the Grizzl-e charger for just 1 car, but they do sell one that will charge both at once. I'm not sure if the method is editable (fully charge 1 then fully charge 2; charge both at half speed, etc.)

With a 40A circuit...
Wow, awesome work.
Sign me up for the double walled replacement brackets ($115+shipping). If theres not enough interest, I'd happily take the adapter plates instead.
I am in for 1 set, and good for whatever size everyone else agrees to. I also agree the 6.3mm is fine, though I like the 9.5mm because it's already proven.
Were you able to make these in 304 stainless?
Another idea might be to have them 3D printed to test-fit clearances.
It would be so nice to get the awning down in-line with the top of the crossbars.
