I have seen a number of posts advising people to release the friction stabiliser handle before reversing or manouevring onto a pitch, apparently it saves wear on the friction pads. However, I had an experience recently which suggests this may not be a good idea.
A caravanner was attempting to reverse his caravan onto a sloping pitch, after several days of heavy rain had fallen on the site (CC, Berwick-on-Tweed). The ground was extremely boggy and uneven and his front-wheel drive car became well and truly stuck, so I offered to position his van using my 4x4. We duly hitched up his van to my towcar, but he left the Al-Ko stabiliser handle in the up position saying it wasn't necessary to engage it. Fair enough I thought, and began reversing. After moving back a few yards, there was a loud bang and I knew immediately that something was wrong. I got out of the car with to inspect the damage, and discovered that the caravan coupling had jumped off the tow hook and rammed into my rear bumper. Fortunately the damage was minor.
I'm pretty certain that the coupling was properly engaged to start with, as the green button had popped up and the black coupling lever had snapped down. My conclusion therefore was that the friction stabiliser being dis-engaged allowed sufficient free play in the coupling head to allow it to jump off as described under the stress of the manouevre. After coupling up again, and this time engaging the friction stabiliser, all went smoothly and I had no difficulty in completing the exercise.
Any comments?
