Welcome to modern expensive vehicles in general. It sucks.
At the end of the day, the car did its job and kept you safe. You can always get another one.
Great numbers! But I would be weary of increased tire wear in a city environment which I imagine is where you do most of these rides? Unless you drive super duper gently and accelerate and decelerate very gradually.
Thing is you won't be getting 410 miles of range at road trip speeds, so probably not worth an upgrade if all you're looking for is noticably better charge speeds and range. In the real world, your overall experience will likely not be too much different than what you already have.
I don't think any Rivian will match the reliability and longevity of the 2UZ powered Landcruisers and LX/GXs, sorry to say. Sure the gas costs over hundreds of thousands of miles may be eye watering but other than rust those little trucks are borderline unkillable with half decent maintenance...
Wonder if this happens specifically when there is a hanging water droplet on the rear camera. Maybe turn on the rear camera and see when the truck ghost image appears!
I'd be less worried about the miniscule extra tire wear, and more concerned with the hit in ride quality you get while in low. If you're driving around in low and that doesn't bother you, then just send it.
Agree with above on charging at home. 110V will make you hate the car and it's a non starter for ownership with your predicted miles. Get the 14-50 outlet installed at a minimum.
Street tires are what you want if you're not off roading which it doesn't sound like you are. They are quieter and...
I don't know the boundary waters well, but I always suggest visiting the UP. Copper Harbor area is really cool. You can camp at High Rock. Some of the coolest and most remote camping I've done was right there, outside of Colorado at least. The R1 should have no trouble making it down that trail.
