A cooktop makes a kitchen for many people, but cooking makes a big mess in a small van. Splattering and aerosolized oils permeate everything, but an air fryer contains the mess.

America’s Test Kitchen recommends drawer style air fryers, but allows that some people may prefer toaster oven-style appliances.

Chilled water on tap is a luxury in a van. Chilled sparkling water is truly posh. The Everpure Exubera (model EV983050) in the video is about $2,000 and out of stock everywhere, but products with similar features are available on Alibaba.

The Loch Capsule dishwasher started on Kickstarter. Cleaning dishes (and the water consumption it requires) is one of the biggest barriers to preparing meals in a van. The Loch Capsule uses less water than hand washing, and eliminates barriers to cooking.
