The damage to the motorhome turns out to be very minor (the fibre glass roof hasn't suffered very much at all and can be repaired rather than replaced) and is only going to cost about £2000 to repair and we're going through the usual process of corresponding with Norwich Union to sort it out. They are being very good though and hopefully we'll get the go ahead in the next couple of days. Then, book it into Brownhills Motorhomes in Newark for the work to be done.
If it doesn't take too long to get it fixed, the plan is to spend the last month of our holiday heading north into Scotland (with a bit of walking in the Yorkshire Dales on the way). I'd like to take Jude up Ben Nevis (but I might end up doing that on my own!), and spend some time at Fort William and the Highlands.
Let's hope the midges don't get us....
