I guess the trick would be to use an inverter and operate the fridge
from 120VAC. There would be a bit of efficiency loss due to the
inverter, but if it's only hooked up this way while driving, it should
not be a problem.

So, other than the surprise the thing gave you after five hours of use,
how useful do you find the RC3000?
