As a relatively new caravaner I will say this I drive to my abilities and to the road conditions and always in a safe manner, I never go above 50mph and if you dont like that then pull over for ten mins and let me get well in front of you or go another way,,,,,, the speed limit is a limit not a "TARGET" I pay my dues just like most of the other road users if you dont like it let the train take the strain !!!!!!
