I am of the opinion that this so called hobby is now a large money-spinning industry and what was an alternative to going to hotels, holiday camps, etc and liked and afforded by many in the 1960/70s has now become far too expensive for the average family man. To buy a decent family caravan and tow car requires approx £35-40000 pounds and then there is the insurance on both, camp site fees, etc., on top. How does the average family with 2.4 children manage to afford it these days. My wife and I are lucky in that we have reached our standard over a number of years and the children are now independant of us and the mortgage is paid.
