Hi there, I am just back from camping and had a great time. We have started looking for a touring caravan and we recently viewed a Lunar Delta 610-4. We were told it was 1997 but it's hard to tell. It is a little shabby around the edges, has a small tear in the caravan which has been siliconed. The blow heater does not work. Other than that everything is good and the man will accept £2400. What do you think? How much is a blow heater? Would the tear cause any problems? Thanks
