UK Caravan Registration in France

I am in the process of completing the R101.4. to register my caravan in France.
I have received a lot of help already (thanks Luiz). (I do have an English Translation of the document).
Using every document I have relative to the caravan, (including the 178 page COC from AL-KO !!), I have completed a lot of it.
However there are several questions where I am not actually sure what information they are asking for.
Is there anyone out there that has recently transferred a UK Caravan to French plates that would be able to advise me please ?
My caravan is a 2001 Bailey Ranger 460/2.
