I purchased a River Quiver four rod holder for my truck from a retail store. For some reason, no fault of Riversmith, installation instructions were not included with my rod holder. I've been informed that the instructions say that for some racks (mine is a Yakima HD Rack and cross bars) longer connecting bolts are required. When I eventually contacted Riversmith, they immediately sent out the correct bolts for my rack. Since then, I have installed my Riversmith 4banger rod case and I am very pleased with it and with the quick response I got from Riversmith.
