Hello all, the remark by many that they do not know that a caravan is on the back.Pehaps its me as i drive by the "seat of my pants", i know whether a stone is in the tyre and host of other things such as unusual noises that my wife cannot hear but to me it means something even if its the tarmac singing to me. As to the unit on the back, maybe on the motorway you might not be aware of the pull feeling, but bumpy road surfaces you get the efects .Welcome any comments.
