The wife loves camping really, she managed the entire Outer Hebrides on the Tenere recently but has decided hotels in Luxemburg ! haha.
I wont manage to meet up in Europe, but I should manage a coffe in Livinstone, Will let you know sharpish,
If you`re heading up the East coast then imo, you either head straight up the A9 to Inverness or go along the Fife coastall road via St Andrews etc,to Dundee and again, stick to the coastal route after Aberdeen,
The A90 is a dire road, so I would either avoid it, or use it to visit a few places on route, Arbroath, Stonehaven etc.
The A9 passes through some beautiful country and is a far nice road, but you miss a large chunk of the East coast. Up to you really. My vote would be A9.
Once up north the world yer oyster. When heading back down, do not miss the Kyle of Lachalsh raod out to Skye, one of the most beautiful roads Ihave ever ridden, just be aware of folk behind you as you pootle along at 30 looking at the mountains !! lol
