Hot Water At Pennsic: Is This Better than Our Current Camp Tech?

This Portable Tankless Water Heater is much smaller, uses the same propane tanks, and is actually designed to do what most Pennsic camps want it to do, unlike a big tank water heater.

I'm not suggesting we get rid of what we have that works, but maybe other camps who are revising or creating their shower system could use something like this. If we didn't have a solution already, this would seem a no brainer.

Then again, is it worth the cost to stop having to haul that big thing around? The owners (Roland and Theo, I think) might be able to sell the old tank for more than one of these costs!

On the other hand, we might need three of them: one for each shower, and one for the sink. Other camps might need less.
