Took delivery of my Launch Edition Black/Black a week ago and I am having a terrific time with my 10 year old grandson ( who is the official expert on Rivian).... he has read the entire manual._I have tried to get my wall charger installed efficiently on a pedestal just outside of one of my garages. I started the process with Rivians vendor QMerit. The quoted $4200 to install a 60 amp breaker ( in a 200 amp panel that already exists) and about 25 feet of 4A wire. Seems like a bit of a press by their subcontractor. I am located just outside of Dallas and I believe I am the first Rivian in Rockwall County so no one has any experience installing this particular wall charger. There are lots of Tesla's so it cannot be much different. Can anyone tell me what they were charged for a similar install so I might estimate what is fair.
