    Has anyone used a Y-connector with dual TT-30s, one on each phase? It should nominally deliver 30A at 240V, so charge at 24A. I could make one, and they have them for sale on Amazon.

    Yes, I know the setup is not to code/"legal", and one could touch a hot plug. That's not my question.

    Has anyone actually used this? How often? How hard is it to find separate TT-30 on opposing phases? Did you have a TT-30 extension cord? Were campgrounds very opposed to this when they found out?

    I'm off to a camping trip to Baja California this winter with a trailer. No 14-50s, Chademos, J1772s or Superchargers south of Ensenada. I've looked at the Tesla hotel destination chargers, which may or may not be available to a non-guests. Round trip Ensenada - Cabo San Lucas is about 2000 miles. A full charge with a single TT-30 is over 24 hours.

    Looks like there is just one welding shop about halfway down, so they probably have a 6-50. There are a few others in the south: Cabo San Lucas/Las Paz
