Hi

I have recently purchased a Swift Challenger which requires some work, including replacing the skylights. I need to make sure Im measuring up for the new ones correctly. Is from the inside, ie the size of the hole? Or from the top?

Hope someone can set us right! New to this!!

See here http://www.1carpc.co.uk/wcdr/mini-heki-install.htm , remove the vent bottom trim inside the caravan pic 4 , measure the hole in the ceiling pic 5 , also measure the ceiling thickness, you can do this by putting a rule up the gap between the ceiling and roof vent , roof vents come in a few different sizes eg 400mm x 400mm , 380mm x 380mm see here . http://www.leisureshopdirect.com/caravan/ventilation/mpk_rooflights.aspx

Perhaps the answer is to replace the entire unit with something like a Mini Heki which is 400mm square. If there is sufficient wood in the mounting frame in the ceiling, removing 15mm all round isn't that difficult if you are handy.

Hi just reading measurements on the sky lights. Mine is 37x37 mm interior aperture, and the outer cover lid is 46x46 so large lip on lid , I cannot find a roof light on this planet the same . Caravan is Deffleff’s newline 1993 model . Just need the roof cover replacement but at a loss as what to do.
