As I recall,there are still some Bedouins left.How does modern day society view these,Dashing,adventerous folks?Would it be difficult to dress in their(Bedouin)attire,& travel to the various stores to purchase the equipment you desire?Surely nobody would question their motives,would they?Afterall,most of what you are seeking,is used by them on a daily basis.Would it be too difficult to use their accent/slang to give decent authentication to questioning merchants & such?Good luck with your endeavours!
