Just went out to check the steadies on our Coachman VIP due the horrendous weather and when I tried to tighten one of the rear steadies, the handle just went round and and no pressure on the ground. It wouldn't wind up or down. I checked them last December (similar weather) and they were fine and the van hasn't been moved. Could the thread have gone, or googling it seemed to suggest a nut needed replacing. They are heavy duty steadies and again from googling seem to be Stabilform - but where do i get the parts from ? The van is 10 years old and we have had it from new.
