Hi folks can anyone help please. is it possible to replace the material only i.e. the thermal blinds into the cassettes myself. I have been advised by the bailey dealer over here (NI) that i have to have them fitted by them complete. at a cost of approx £300. A bit expensive. Our dog chewed them through after being left in van on his own. (for a very short time) before all you owners complain of leaving the dog. We are planning sometime over to the lake district and blackpool next week. so i would be grateful for any advice anyone could pass on.
