Hi Gilbert
We only use ours twice per year. We have our "big" trip on the continent between April and early July, lasting between 6 and 12 weeks. Then we have a late season trip of about 3 weeks, usually in this country, but have been to Ireland.
Do I consider it gives value for money? - well if you just look at the holiday costs nothing else comes near to competing for three months traveling every year in comfort. But if you include running costs - capital tied up, depreciation, insurance, storage, breakdown cover, servicing etc. then it probably doesn't.
But you don't buy a caravan to save money, you buy it because you love the way of life and the freedom of being able to tour where and when you like.
