Hello Julie, welcome to the wonderful world of Talk Morgan and Morgan ownership.
Skye is beautiful and a great place to tour. I've enjoyed several motoring holidays there but never in the Morgan. The roads I found to be good. Obviously narrow in some places but not so much as you may fear. Being extremely old( and therefore extremely wise) I remember my first crossing to the island by the ferry at the Kyle of Lochalsh which did ground the sump on my car of the day. But now they have the lovely bridge so no worries! You will have a great trip I'm sure.
Andy
