How long do static homes last?

Leisuredays insures holiday caravans up to 25 years old, which is proof they do last a good number of years. Some holiday parks have age limits, often 15 years after which you might have to replace your caravan. Some park operators do not have an age limit and allow you to stay on a pitch as long as you like, so long as you adhere to the terms of your agreement, and maintain the lodge or static caravan in a good condition.
