Really?
According to Kelly Blue Book, the average new car price in the US is $49,500. The base Tesla Model 3 is $42,990, about $35K after federal tax credit.

Maybe you mean “if you can afford a new car….”

If I catch them in time before they order it, I have my customers get the hardwired version, that way I don’t have to pull a neutral.

The the standard charge cord is included with the car. The customer purchases what ever adapter they need to connect at their house. They can choose a 6-50. I'm not sure why so many choose the 14-50 unless their Tesla sales person recommends it. My neighbor ordered a Model S recently and their sales person recomended a 6-50 unless they had an existing receptacle. The neutral pin on the 14-30 and 14-50 adapters doesn't connect to anything.

Correct, but some controllers require it. The EV doesn’t. But some manufacturers such as Eaton required a neutral, because the contactor coil they use is not rated 208/240, so they use a 120 volt coil to make it universal in the states. I installed a lot of Eaton commercial chargers, and that’s what the engineers gave as the reason.

Eaton only makes commercial and fleet charging equipment, no residential.
And they are all hard-wired, so in the context of receptacles for residential EVSEs currently available, none require a neutral.

As for the reason a Tesla buyer would opt for a 14-50 over a 5-50, the reason is that you can plug in and charge at an RV park or campground, if necessary.

That makes sense for that recommendation.
Are Teslas towable? Not very green if you have to drive two vehicles. Sure you could probably trailer it, but it would be really heavy for an RV. Probably work for seasonal camping, but then you would have to rent two sites, or unplug your RV at night. I haven’t seen any campgrounds yet that have charging stations. Could be though at high end rv resorts.

Isn't that what adapters are for? RV and camper owners are used to adapters BTW.

5-50 would be 50 amp 120 volts guessing you meant 6-50.

No. The Tesla use case is that you’re out in the middle of nowhere, need a charge, and the only thing in the vicinity is a campground. You drive to the campground, rent a site, and plug in.

Now that that there are EV trucks such as the Ford Lightning, there will be people towing their campers with them.

You won’t likely see charging stations in campgrounds, not needed - you just plug your portable charger into the existing 14-50.

Yes, typo.

Given the issues with melting receptacles, I’d be careful adding an adapter to the mix. An additional connection to generate heat.

Those lightnings won't be able to pull a big nice trailer far but an airpdynamic ultra light one could be and still get somewhere.

I’m sure the campgrounds would be more than happy to rent a space to someone using almost twice the power an average rv uses! LOL!
