We have a spares box for the two V8 Discoveries, contains most things up to a front and rear wheel hub. Getting spares can be a nightmare in Europe, even if you can do the job yourselves.
Water pump
Aux/fan belt
Set of spark plugs
Rear hub
Front hub
Clutch slave cylinder
Clutch master cylinder
Spare clutch (at home in the workshop)
Ignition coil pack
Plug lead set
Bulb sets
Propshaft donut rubber coupling
Spare front propshaft
Propshaft U/J and centering bearing
Wheel nuts
Propshaft bolts and nylocs
Trailer wheel bearing kits
Half shaft nut
If that sounds like a lot, we tow our 3.5 tonne show trailer in Europe and cover 2000 miles most years. What we don't carry we can get our son to ship out overnight by UPS from the factory where our other spares are kept. In 2014 we had a coil pack connector failure and our son had to drive nearly 300 miles on 7 cylinders.
The front propshaft is a special bit of kit with three U/J's, one at the front and two at the back in a double cardan joint where it attaches to the transfer box.
The replacement was waiting at Villey le Sec next day when we arrived. If you have that kind of backup then life isn't too bad.
No problems on this year's trip!
B****y hell Peter,you must have been in the boy scouts
