I have read with interest the different ideas many companies have when trying to sell roof ID to motorhomers.
My business involved the manufacture and supply of emergency services fleet markings which included roof marks. In the early 80's the government suggested these as a means of identification by air support units. At that time a size of 6 inches was agreed. By the early 90's this size was decided to be to small so 12 inches was then used. As time progressed the mid 90's saw yet another alteration come into play. The helicopter pilots agreed that in order to clearly read a roof mark it had to be 18 inches. This is now still the rule and any larger would mean much bigger roof area. We roof marked the prison vans at 18 inches much earlier than police vehicles.
My warning to funsters purchasing roof ID is to state 18 inches high and use the last three digits of your vehicles VIN Number.
If you need any advice please let me know. I also have a contact for the roof marks.
