What is an experienced tow driver?

 Having driven large Motorhomes for quite some years we are about to take our maiden voyage in our first caravan, so we are looking for tips from the more experienced of you. So what is an experienced tow driver?

I should say we have bought the CC towing DVD and have read loads of advice on towing but it's the little tips from the more experienced amongst you we are after.  For example, slowing down when going downhill I am sure is not just about the brakes overheating, is it?
