I am really excited about having an SC there for trips from the SF area to the Yosemite region. Then I just need to find places to stay near Yosemite that can provide me with a 240V outlet for overnight charging. I am aware that Tenya Lodge near Fish Camp has two EV charging stations but my wife and I prefer to stay at smaller, more intimate places. I'll be looking for places near Groveland, Mariposa, or Oakhurst.
I just took a look at B&B's on tripadvisor for Oakhurst. There are some really great looking places to stay! My guess is you could start calling them to find one with a 14-50 dryer outlet you could use. If you kindly explain the situation and that there would be other Tesla owners interested in staying AND that you can list them on Plugshare, you may find someone willing to install a 14-50 for future Tesla visitors, even if they do not have one already. As you likely know, depending on where their 240v is, a 14-50 install may be less for them to have installed than a couple of night's stay.
For example, there's a little place in Independence, Ca, (Ray's Den) along 395, for which I am paying the $300 for them to install two 14-50's. In return, I will get 6 overnights free, so its a win-win for us both. If you do give this a try, forward them the info from Tesla's website about 14-50 installation so they can show their electrician.
