I also have ev sport line rock sliders
Rivian mobile service came out to do tire rotation no problem
they even thanked me for having the rock sliders which made it easier for them to lift
Had the same issue
Do not use the white pig tail breaker (GFCI)
It causes a problem since the rivian charger already has that built it
I swapped it out for a regular one
No more issues after that
solar tonneau would be an awesome idea! Unfortunately I have a r1s so I would have to go another route
I guess my best bet is loading my trailers roof with solar and trying to charge off my camper in case of emergency
