Hi we are getting our 18 year old LHD Frankia A class to go out for a trip.We are very much newbies at motor homing, but I am good at sewing etc (Snow and leaves on our mountain track stopped us up to now after our January slide to the edge on slippery leaves......):Sad: We have a problem with a blind in the rear U shaped lounge offside side window blind. It is in two parts; the top bit that pulls down is a fly screen ; it clips to the plastic blind which pulls up from below. The blind material is a textured hard plastic which,after a lifetime's use, is a bit crackly and stiff to pull up. 1. Is it possible for a DIYer to replace this material with fresh blind material? 2 How do you get at the fixings below the tension spring the roller etc ? 3 It's irritating to have the blind not working, but would it be better to leave well alone. A dealer would probably charge the earth to do this? Many thanks for any advice.
