Look very carefully. You will see a loose wheel bolt. Caravan was in a secure storage facility & this was discovered at point of service by ourselves.
IT IS THE RESPONSIBILITY OF THE OWNER TO CHECK WHEEL BOLTS AT THE START OF EVERY JOURNEY.
Regardless of when your caravan or trailer was last serviced or worked on, if you leave it unattended at all, check the wheel bolts before you move off.
This could so easily have had serious consequences.
