Plan a drink spot at a parked-truck stop
Keep the table separate from loading work.

Park and secure first
Follow the vehicle’s instructions for the stop. A bed liner or tailgate can be ridged or sloped and is not automatically a level table.
Clear the work route
Keep the drink outside the area used to unload gear or step onto the tailgate.
Pack before travel
Put drinkware into appropriate travel storage before moving. A freestanding base does not secure it in the truck bed.
