That's very astute of you. I called around and you are correct, 100 lb
tanks do not require the same weird three cornered valves that now appear on the smaller tanks. The dumb cow at the RV park didn't know what she was talking about. Sorry if I sound pissed, but she wasted 1/2 of my day and $10 to get there and back. Hopefully, she'll spend the rest of her life managing a RV park.
As for how I'll move 100 lb tanks around in the third world, by handcar, wheelbarrow, dolly, donkey, tricycle or whatever. People in the third world are infinitely better at logistics and transportation than we are here. You can cross
Panama faster on public buses then you can drive yourself, and it costs two dollars.
