The HDT Expando Van Vehicle Boot creates a sealed passageway between an Expandable Van shelter and any HDT soft wall shelter. The boot features an articulating frame to support the fabric and a weather seal on both the vehicle and shelter ends of the boot. The boot connects to any HDT shelter through the AirBeam® door or vestibule as well as DRASH® and Base-X® articulating frame doors and works with all HDT soft wall shelter models.
