What's the best way to keep the water and dust out of the bed? Rhino line the floor and walls and add a topper? Please give me any suggestions you can, I need to make recommendations to my boss early next month for our next batch of trucks (unfortunately, GM Duramax/Allison 4x4, corporate contracts tell us which brand we'll use, AND they won't get manual trans- not enough people can drive them anymore!!)
