Hi critters,
Not sure what your cubic foot restrictions are, but I really like my smoke hollow unit that I bought at Home Depot. My reason for purchase was size and functionality. Most of the small units only have one loop burner that covers the whole grate from underneath. With those you are either all hot or all warm. This little unit has three separate burners so I can control my heat if I’m cooking more that one item. A big plus is the center burner heats a smoke tray so you can put in wood chips and to a slow smoke. The lid is tall enough to let you fit in a whole chicken or tri-tip or brisket. It’s all stainless steel and has latches that keep the lid closed when traveling. I’ll attach some pictures so you can see how I arranged it in my storage compartment and what the unit looks like.
