The free check tells you whether the number reads, whether the caravan or motorhome is on this register, and how many flags it carries. The report tells you everything the register holds, with sources, and where to buy the data it does not hold. A motorhome can be found by its number plate.
The industry register for touring caravans is CRiS, which sells its own check for £17.95. We are not CRiS and we are not connected to it.
