Nealsyard Posted August 13, 2018 Share Posted August 13, 2018 Would anyone be able to tell me if the rear section on the Rapido 741 has an aluminium layer? I am considering a roof aerial for the the radio and need a ground plane. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted August 14, 2018 Share Posted August 14, 2018 Rapido has used two types of roof construction - one is normal with the roof comprising a single-thickness sandwich-panel and the other (on their more expensive models) is peculiar with a secondary skin ‘floating’ above a lower ceiling panel. However, as Rapido’s roofs (whether single or double ‘layer’) are skinned with polyester material, I can’t think of any credible reason why a Rapido roof should have a metal layer anywhere in it. I suggest you either assume that the roof of your (late-2000s?) 741F does not have a metal layer in it (which is what I’d do) or see if a Rapido dealership could give you a 100%-certain Yes-or-No answer, or try asking the Rapido Motorhomes Facebook group https://en-gb.facebook.com/RapidoMotorhomes/ Link to comment Share on other sites More sharing options...

tonyishuk Posted August 14, 2018 Share Posted August 14, 2018 I have a suspicion that the top panel below the floating roof membrane is aluminium on our Rapido 7090 2009 model (3.5 ton, 24 ft) When we had a serve leak (roof bar mountings had no mastic under them or sealing the screws) I queried what would happen to the roof. It was a while ago, but I seem to remember that was not to worry as the roof board was aluminium and would not be affected. The membrane was lifted as much as possible and aired for a couple of weeks to dry out. So said the dealers ? Rgds Link to comment Share on other sites More sharing options...
kevina Posted August 14, 2018 Share Posted August 14, 2018 You are correct Tony. On Rapidos with the floating outer roof the top skin of the structural roof is aluminium. Whether that is the same on a 741f I don't know but looking at a couple of pictures indicates it is likely. Even if it is, how the aerial could be bonded to it, and made waterproof, is another question. Link to comment Share on other sites More sharing options...
tonyishuk Posted August 15, 2018 Share Posted August 15, 2018 It may pay to phone & ask Rapido Dealers at Wokingham for advice. They give the impression of organised chaos but can answer most Rapido questions.
