Happened to look under our Swift Charisma 535 2010 and saw the rear panel where it joins onto the floor base has large gaps where Swift have not put enough screws in or so I think.I did put three more in but the panel still has a bow and I was concerned that if I did put another one there the panel might split. I also inserted some more mastic in the gaps except where the wire go into the bottom light but again thought have Swift left it like that for water to drain off. The other thing which concerns me is the rain and wind going up to the panel will make the water go up into the rear panel and maybe further. Any thoughts welcome.
