A few things I forgot to mention:

Don't leave your vehicle on the side of the road for any reason, the next time you see it, it will be a wreck, the windows would all be smashed and the roof, hood and trunk will be all beat up.  We have passed a few in that condition.  I don't know if the Abos drive up and down the highways until they see something they can damage or just how this happens but we were warned about it and it seems to be true.  We were talking about caravans vs. 5th wheels (goose-necks) and were told that if you break down in a caravan, a tow truck will come, put the vehicle on a flat deck and tow the caravan.  If you have a 5th wheel they have to leave it because they don't have the ware-with-all to tow it.  An elderly couple were travelling up the centre and they had a break down of some sort and when they got back to their new 5th wheel, it was totally demolished.  There was not a thing they could do about it and were just totally devastated.   I don't know how insurance works in this country, but you have to be very careful.  We are not to go on any gravel roads or it will nullify our insurance on the van.  We could be in big trouble when we get back.  You have to read the fine print.

They also have road trains here.  They are 18 wheelers towing up to 5 trailers behind.  The roads are so narrow that you have to pull way over, almost in the ditch and stop for them to go by because if you don't they tend to go off the road and spray gravel all over the place, they can also suck you over.  Some times it can be pretty scary.  We have been lucky and have only run into the ones that have four trailers, it is a real nail biter getting past.

There are wild camels here also, I didn't know that until we saw a couple.  They do look odd here, however, it is a good place for them being desert and all.
