You and I are on similar paths, although my trip is only 600 miles one way. Plans are to leave in the next week or so.
Change the fuel filter if you haven't for sure. Unless you've looked one never knows what's in the bottom of the fuel tank that can get stirred up and plug filters. Now that I think about it, carry a spare.
Again, if you haven't already...go completely through the brake system. I know a lot of European countries have very strict inspection requirements compared to the rural states in the USA (my state has zero inspections of any kind). That said you may have either dealt with or will deal with the safety related items such as tires, brakes and suspension details.
Lots more to discuss but sounds like you have a lot of time. As Scooter mentioned, just start driving it.... as often as possible and the weak areas will pop up.
Good Luck, Ron
