Not all recreational vehicles are created equal. The smaller the RV, the fewer creature comforts are apt to be included. That doesn’t mean owners can’t accessorize units themselves as space permits — and the new iWaveCube is a portable, fully functioning microwave oven that displaces less than one cubic foot. Weighing just 12 pounds, the 600-watt microwave plugs into a standard 110-volt outlet. The quiet, super-energy-efficient unit features an 8-inch by 8-inch by 6-inch (.3 cubic feet) heating cavity and a view-through door. The oven control panel is built into the top of the microwave, near the unit’s built-in carry handle. Available in silver, white and black.
