Portable USB-C monitors like the ASUS ZenScreen (15.6") or Lenovo ThinkVision M14 offer single-cable connectivity and low power consumption. For higher resolution, the Mobile Pixels Duex Pro attaches directly to laptops. iPad tablets can function as secondary displays using Sidecar (Mac) or Duet Display (Windows). Consider monitors with built-in batteries to reduce power draw from your van's electrical system.
