As the name implies the HCI is a one make club catering only for Hymer motorhome owners.
The membership is currently around 550; each membership usually being for a couple, meaning that there are around 1000 people in total.

The HCI holds an Exemption Certificate from the D.E.F.R.A. enabling us to hold rallies away from licensed campsites in Britain.  Rallies are organised by members for members and there is a varied programme of events in different parts of Britain throughout the year.  There are also occasional tours and rallies abroad. Spain, Germany, Belgium, Austria, Italy, Hungary, Scandinavia, Croatia and Slovenia and many areas of France have been the destinations in recent years.
