I saw these boxes made by Plano on an overlander website. They seemed like a great size for putting them on my roof rack. Their not super heavy duty or waterproof but they seem to seal well and can be locked and have wheels on one side. I was finding them for anywhere from $40-$50 plus shipping each but just found them on the walmart website for $20 and free shipping over $50. I bought 2 and a cheap gun case to total $50 with no tax or shipping. Anyway thought if share as it seems like their a great option for those of us who don't need heavy duty pelicans etc.
