Well I have just ordered a Frontier Stove and water heater jacket a few days ago as I am expecting some national fuel shortages this winter. It should be very flexible not only as a stove, but as a space heater and water heater (for hot water for cleaning cooking utensils, washing and showering). Light enough to be luggable and compact enough for vehicle carry.

A more substantive stove (more expensive) called the Traveller Stove is also available;
