Please can anyone tell us where we can get hold of Motorhome Corner Steadies for the rear of our van. We have a Hymer B544 and the minimum distance (on level ground) from ground to the fixing point is 55cm so standard caravan steadies won't do. There are already fixing holes in the chassis where the previous owner removed steadies so we are assuming we can just bolt new steadies on to give more stability when we are parked up. All help appreciated. Thanks.
