Pack the trip on paper before loading the car
Packing a car starts with the load on paper.
Packing a car starts with the load on paper. List the people, luggage and equipment before deciding what can travel together.
Consult the owner's manual and vehicle labels for loading limits and restraint instructions. Physical space and permitted load are different constraints. Include accessories and any roof or towing arrangement only within their applicable requirements, seeking qualified guidance when needed.
Give each item a place
Plan for appropriate securing, visibility and access to essential equipment. Do not leave heavy or loose objects where they could move into the passenger area or interfere with controls. Keep emergency items accessible in the manner recommended for the vehicle.
Consider the journey sequence. If a bag is needed at the first stop, burying it beneath everything else may require an unsafe roadside rearrangement. Pack and adjust in a suitable location rather than beside moving traffic.
Before departure, check the actual arrangement against the plan and the relevant vehicle instructions, including tyre guidance for the load where applicable. If the load cannot be accommodated safely, reduce it or choose another transport arrangement. The purpose of planning is to discover that limitation early. A successful trip load is one the vehicle can carry appropriately, not merely everything that can be squeezed behind a closing door.
