Here is the Best advice out there, as I have done it many times. First take a WOMEN! Second, Buy some Local art, pottery or some other junk that a tourist would buy. Second, Change you appearance after you buy your gear. i.e wear a hat and glasses and ditch them after you are done buying, and change your t-shirt. Wear average jeans, nothing that stands out. I suggest ONLY driving to bring back gear. I have done it both ways, and I tell you driving is much safer. Hide it somewhere they would have to take apart, EXCEPT the air filter housing, spare tire well, door panels. There are alot of other places. If they ask what you visit is for, say "Me and the lady were doing the tourist thing!" show them your pottery and your home free.
