Does anyone have experiance with a Down River Equipment frame and the NRS cooler mounts. The DRE frame has a bigger diameter tube than NRS's so the metal brackets dont fit correctly. It seems that I can bend the brackets enough to get it to fit but I don't have any idea if this will really work. I will be carying a fully loaded 150 qt cooler (beer) plus me (220 lbs

) so I don't want the brackets to start bending more and dropping my cooler on to my floor in the middle of the trip. I know this will probably void the warranty from NRS. Any info will be appreciated. THX, kris
