..IMHO most RV'ers have NEVER towed any type of trailer in their lifetime. Yet. Because they own a truck or Suv they go out and buy an RV trailer and hit the road with absolutely NO experience or training on how to haul a trailer 'safely' OR what to do in case of an emergency while towing one...

And so how did you get your experience and training?
