I'm hoping someone who has the same MH as us can advise. We have a 22 plate Burstner Harmony Line Lyseo TD680G. It has the drop down double bed over the loung area. There are two skylights in the main habitation area. A large one directly above the kitchen area and a smaller one directly above the the double bed (obviously, only accessible when the bed is down). A few days ago I received a call from our storage area to say we had left the small one open (it was raining). This was odd because I cannot recall ever opening it, given it can only be done with the bed down). Sure enough, it was not only open but standing vertical. On inspection, I noticed that there seemed to be no retension springs (my word) to stop the wind pulling the cover open when it was positioned in one of the 'open' slots (hope that makes sense). Looking at the large skylight on the kitchen, this has a long retention spring either side of the skylight. I'm not sure what the technical term is for these skylights but should they all have retention springs, irrespective of size?
