Interesting!

I always thought that three-prong only plugs and receptacles was on the way out for things with that amount of power, so that they had a neutral and a ground plug. Guess not!

The electrical code is a crazy, complex thing....
There are the two different kind of 240V 3-prong plugs.

All 240V have to have "Line 1" and "Line 2" to achieve 240V. The 6-xx have the two lines plus ground, (so are 240V-only,) the 10-xx have the two lines plus neutral - which means you can technically draw 120V from them, but they don't have ground, which is now considered pretty much required for safety.

14-xx are four-prong, which have the two lines, plus neutral and ground, so you can draw 120V from them, while having the safety of a ground.

The main reason electric clothes dryers used 10-30, and are moving to 14-30 or 14-50 is to have the 120V available. Some dryers would run their "control electronics" on 120V, while using 240V only for the heating element. And of course by using a "dual voltage" if you have a gas dryer, you could use an adapter to run its electronics on 120V. (Since gas dryers almost exclusively use standard household NEMA 5-15 plugs.)

On the off-chance you need an RV TT-30P to NEMA 14-50, this one worked for me, but note that it's only 24A charging at 120V, so it's quite slow.

Certainly get a J1772 to NACS/Tesla adapter for Tesla Destination chargers, but I haven't had to use one yet. I've had the Lectron and now the A2Z. Really, the CCS to NACS adapter is much more useful.

As for the Tesla membership, remember that to use that you need to activate the stall with the Tesla app *before* plugging in or else the truck will just use Plug and Charge and you'll be billed through Rivian.

But really, don't over think it. The nav in the truck is pretty good. I always have PlugShare and ABRP that I use alongside the truck nav if I'm going into an area with few chargers or really want to maximize things. Don't rely on any DC chargers that are at car dealerships. They could be available, but often they're either behind a locked gate, ICE'd, or otherwise unavailable when you need them. I've probably got 10k+ road trip miles in my truck at this point and 1000 miles towing my race car outside my local area.
