We have the same brand of induction cooktop; it works great and I like that we can take it out of the van when we cook something that splatters. Our Griswold cast iron skillet works wonderfully on an induction cookstop:

We have a backup butane stove that's great for setting on a picnic table, doesn't take up much room and doesn't hit the battery like the induction cooktop.

I bought a case of the butane canisters 2 years ago and we've only used up one canister as we just don't cook as much as we used to when we're on road trips. We end up using the microwave more than anything else.
