already have the electrician lined up..all the ebay ones won't arrive until well after I take delivery, I do about 70 miles round trip daily so the 120v won't work.
It might do for a few days, especially if used in conjunction with other local charging options. If you're home for 10 hours overnight, then a 120v outlet would regenerate about 50 miles; if you're home for 12 hours, that goes up to 60 miles; a 14-hour charge nets 70 miles of range. Thus, you'd be losing 0-20 miles of range per day, net after your commute. If you're getting an AWD LR with 310 miles of range, and if you start with a near-full charge, then you could easily go for a week or two like this before you ran into trouble. Even an SR or SR+ would last for over a week. If you can charge for longer on weekends, this charging schedule could sustain you for quite a while. Add in an occasional top-up at a Supercharger or even a public J1772 Level 2 charger and you could get by indefinitely like this. Most people prefer faster charging at home, but as a temporary measure, it's certainly do-able. As a practical matter, you've got to ask yourself whether the extra cost of a temporary NEMA 14-50 or ordering a Wall Connector from a pricier source is worth the minor hassle and psychological insecurity of using a 120v charge. Range anxiety is powerful, but based on the information you've presented, I think your concerns are overblown.
I'll probably end up just doing the 14-50 and see how that goes just to get by and see if I'll even need the wall connector. I wanted to install it on outside wall of garage so nice and tidy and can charge in driveway since garage is pretty full of household items
For outside use, I definitely recommend against the Mobile Connector, at least in the long term, since Tesla has not given it any sort of weather rating. As a temporary measure it might be OK -- but as I said in my earlier post, you'll likely end up paying a significant cost for a temporary installation. For that cost, I personally would opt to buy a Wall Connector from a third party at an inflated price instead. Alternatively, I'd look into a J1772 EVSE. Some such EVSEs cost about the same as a Tesla Wall Connector, but if you add a dedicated J1772 adapter, the cost will be a little higher -- but probably not much more so than you'd pay for the extra electrician's visit to wire up the Wall Connector after installing a NEMA 14-50 outlet.
Also, remember that if you have a NEMA 14-50 outlet installed, you'll have to get Tesla's NEMA 14-50 adapter. These used to come with the car, but not any more. Chances are you can get one from a Tesla store or service center, but you may need to mail-order it -- and like just about everything else on Tesla's Web store, they sometimes go out of stock. If your car is being delivered on the 10th, be sure you can get the NEMA 14-50 adapter locally or place an order for it
