A camper salesperson and mechanic published five criteria for choosing a camper, based on experience in sales and servicing. These include: defining the purpose of use before choosing the vehicle type, accounting for dimensions for parking and roads, checking the build quality of the living module and electrical wiring, calculating the total cost with options and fees, and verifying delivery times and after-sales support. It is noted that the final price can reach 1.5 times the base cost, and waiting for popular models takes 1–2 years.
