What a nice trip you intend to make.
Maybe a bit tiring but so exciting.
I agree with most of the MogTalkers, no spare wheels may be hard !!!
Your best enemies (there will be others) will be the potholes.
With no hood it'll be difficult when it rains because in mediterranea the rains comes suddenly and is really intense ...
Anyway it's a lovely experience.
Good Luck !!!!
