I'm planning to road trip down to my Mom's house in Tucson, AZ, and I'm trying to iron out how to charge while I'm there (nearest supercharger is ~50 miles away). She has an electric dryer just inside from the garage, so that's the obvious place to plug in, and I would just need to have the right adapter. Since I don't have either a 10-30 or 14-30 adapter, I'll need to buy one - just need to figure out which one. I'm not sure if she has a 10-30 or a 14-30 outlet, though, and I'd rather not have her back there unplugging it to find out. Her house was built in 1995, and as far as I can tell that was right around the time where new houses started switching to 14-30's, so that seems inconclusive. Is there any way to tell what kind of outlet is there, short of actually unplugging the dryer and looking at it?
