A friend lives in one and deals with the limitations (no overnight stays for six weeks Feb-Mar, telephone cost a fortune to connect, expensive gas has to be bought through the site, etc) for the benefits of living in the countryside (great variety of bird-life including the occasional woodpecker just outside the windows).

The requirement for "another address" is to meet the fiction that this accommodation is not your permanent address - during the six-week lay-off mail would be forwarded to the nominated "permanent address" - maybe that of a co-operative friend?

The same park has a few permanent sites which cost about twice as much to "buy" (you still won't own the land, and the park owner still has a big say in what alterations or additions you might want to implement.)
