Hi we are off to Croatia in a few weeks and only just found out we need a certificate of conformity which we don't have in our paperwork. We are hoping to avoid the tolls through Austria but it looks like we should have this paperwork regardless. We have a Hymer Fiat, have you recently had to get this certificate and how did you get it ? The trouble with Hymer there is no UK number its all in Germany. We have sent them an email asking for help. I will try Fiat today to see if they can help. Also seen this morning online a converter COC ?? has this superseded the COC ? and if so, is this the paperwork i should be asking for, not sure what the difference is , can you advise please. TIA
