Advise taking the grease-gun to keep the pillars sliding, a few tools and some electrical bits.
Funnily enough we didn't do any routine maintenance on any of the cars during the 5250 mile Nordkapp trip. The only mechanical work was done on the 3W when it got water into the petrol, but after over 600 miles on one-cylinder it virtually cured itself and ran faultlessly for the rest of the trip.
These Morgan's are much tougher than many of us credit them for!
