Just had the outer door fly open south of Ayr on way nth.I knew the 3 plastic latches on the outer door were a little worn where they are grabbed by the inner door.If in dought replace these plastic catches.Do not overtighten screws as metal inserts in door will rotate .A new door costs anywhere between $1100.00 to $1900.00 plus fitting ,can not just buy outer door but whole lot including frame.Three week lead time.Looks like insurance claim when I get back home.Apparently pretty common after travelling rough roads.
