A Kitchen in a vehicle is generally limited by space and power constraints. However, many people cook meals outdoors when the weather is nice, and large vehicles often have plenty of room for a full kitchen if desired.
Tailgate kitchens are kitchens built into the tailgate of a vehicle or trailer for use when cooking outdoors, usually at a campsite. They are commonly added to SUVs, minivans, and teardrop trailers, but a kitchen added to a hatchback or other rear door could be considered a tailgate kitchen.
Chuck boxes
A chuck box (or kitchen box or camp kitchen) is a large box for all your camp kitchen supplies and appliances that is portable for use at camp sites. The chuck box will typically open on one side like a cabinet, revealing multiple interior storage compartments which are sized for various items. Often, the door of the chuck box will open down instead of to the side to create a work surface.
