Ours is also a 2.3m body width and I would not like to be much wider at castle ward.
I know it fits through quite easily but it always feels like the gates are narrower than the last time. LOL
Most times we visit we walk into strangford for lunch or dinner and it is amazing the see the number of caravan high level side lights are lying on the ground at the gates.
It isn't a major problem and we all get through.
No idea what the width of the gates is.
