Propane delivery on the Playa?

[KenfromLA]

Hi there! We've got three flame throwers this year. Between the camp bbq and the flamethrowers I'm guessing will be using at least two small bbq tanks a day. Ouch. I really don't want to bring 14 tanks, both for the cost, the bulk, and the safety.

Are there any vendors who will refill on the Playa? (Like Sierra Fuel, except they only do gas and diesel.)
