hi wally
basically common sense stuff mate ,we hit the road 4 mths ago we opted to take spare set of filters ,belts set , and a spare set of wheel bearings and a set for the van
there was a basic bit on oneof the latest dvd,s by fred i think re a total amount of what he would take stacked on the table , a good one he had was a roll of tie wire , and dont forget the good old duct tape ,grey tape of gaffa tape ,saw a good one on myth busters what they could do with gaffa tape, and of course water and spare fuel if your remote , have a good trip
