Responding directly to all messages is a great way to keep a high score. Vehicles with high scores will automatically appear higher in search results. It's important to note that you don't need to reply to every single message within a given request if you have already provided all the necessary information. Your response time is measured based on your initial response to a message, rather than subsequent responses.
By consistently responding to messages and requests, you improve your score and make it easier for Travellers to find your motorhome.
