The article sets out an approach to camper van layout in which the number of travellers, the number of homologated seats, the vehicle's use and the permissible added weight are defined before any work begins. Furniture, kitchen, water, electricity, ventilation and storage compete for the same volume and payload. It states that the van should be weighed and the interior measured with insulation in place before cutting. Under the current Manual de Reformas de Vehículos, fixed furniture, seats, windows, installations and a change of classification may require a project, certificates and an inspection. A decision table covers 2 or 4 seats, fixed or convertible beds, high or pop-top roofs, an indoor bathroom, water, battery and gas autonomy, and daily use.
