Bedouin tents are available for sale in the United States. For example, Mosaik, a Los Angeles store that sells "Art of Morocco," has Bedouin and other tents for sale or rent.
You can purchase a commercially made version. I don't think it would qualify as an official Bedouin tent though. You could probably a nice one handmade if you were lucky.
I am sure you could find these Bedouin tents online by searching websites like Google. Also you can try on EBay, Shopzilla, or Amazon to find your desired product.
