Around 4:53, the front-passenger wheel spins backwards as you're going forwards. That's surprising behavior … and I don't think you're in a quad, so you only have one front motor … any idea how and why it's doing that?

I haven't used "mechanical" RTTs so I don't have a comparison. I like the set-and-forget self-inflating though; I can go setup the rest of my campsite while it's inflating. In the back of my mind, I do worry about the inflating mechanism breaking at some point, but I haven't had a problem yet.

(I haven't but to clarify) are you talking about interior trim, or something exterior?

If you're looking for an alternative/digital rear view mirror, here's a Reddit thread with details of a potential setup. I bought the unit linked in this post during a Prime Day sale — it's ok, but I wouldn't necessarily recommend it because it's not very bright. If you can find another unit...

Maybe something like this…

Apparently, for press events (e.g. mentioned in the R1T unveil here)

I've had the Wildpeak AT3Ws (275/60R20, D-load to match the stock diameter for the 21" wheels) for about 12k miles, averaging about 2.1 miles/kWh. Not much of an efficiency difference between 65psi and 55psi, but the ride is a lot more comfortable at 55psi (which is what I now run).

Technically you don't need to replace a tire with the same tire (doesn't even need to be the same diameter; e.g. people drive with donut spares for hundreds of miles). Open diffs and independent motors means you won't cause any mechanical damage. Eventually you'll probably want a matching set...

Looks are definitely subjective but I don't think either Lucid looks good … their beltline is too high. The Air looks like a cardboard box.

In my experience, self-leveling just pauses, but doesn't cancel, when you open doors. So just turn on self-leveling, go set up your tent or something else, it should be level by the time you come back.

I’ve heard (second-hand) that Rivian is working on an infinitely-variable locking diff for dual-motor configs

It happens every few weeks for me too. Usually, if I notice before I start driving, unbuckling/opening the door/getting out lets it reset to the "roomy" position, and then it'll go back to the right place when I get back in

One of my favorite pics from Gary's Jamboree (a trip organized by the Bay Area and Sierra Nevada Rivian Clubs a few weeks ago).

I have Wildpeak AT3W on my R1T (PDM). Efficiency is not great IMO. I get about 1.9–2.0 miles/kWh around 70mph in Bay Area temps (50s–70s); rarely above 2.2 even in city/suburb driving. But their traction has been great in the rain, blizzard, packed snow on the highway, and a bit of...

As a software engineer, every update makes me a bit nervous, and I won't install updates before trips or when I'm away from home … BUT so far with my Rivian (and 3 years of Tesla updates before that), I've never had an update that brought new bugs.
