I shipped my running boards for 15 dollars. They were the 06 sport style though. I bought them when I was on home on leave and shipped them across the country where I was living at the time (CA to VA). I bought 2 or 3 rolls of bubble wrap from walmart. I think they come in rolls of 15 ft. I took off the mount rails, because I had the luxory of bringing those with me on the plane. They took off a lot of weight, and if your brother has those, then you might be able to save. I then wrapped each RB in an individual layer of bubble wrap. Taped them together, and THen put remainder strips of bubble wrap around both of them for further cushioning. I'm 99% sure I mailed them prioty but it cost me 15-16 bucks. If your brother needs the rails too, you can probably fit them in 2 flat rate boxes from the USPS. Probably 35 total.
