I checked them out last year and couldn't justify the price, think they have come down in price a little bit since then. Guess it's a bit of a catch 22. Until they sell in any numbers the price will be high.
i saw them on a caravan programme on tv and thought what a great idea,first thought was no damage to caravan by poles did think it was a bit pricey would like to see one ,maybe at glasgow caravan show!!!
