Riversmith exceeded my expectations. The Euro with quick release mounts was on backorder, so I called and spoke to a very friendly employee who informed me that the quick release mounts were unavailable and would probably arrive in late December, with my order to be filled in early January. To my delight, about a week later, my River Quiver was delivered before Christmas. The service was amazing and the unit was well-packaged, with nothing inside the box able to rattle or rub.
The fit and finish of the Quiver are beautiful and it was easy to assemble. Although having two people would make the initial setup easier, I managed to complete the assembly and mounting solo. Space on the 4Runner is at a premium for the initial mount and adjustment of the quick release mount, so patience is definitely required. Future use and mounting should be very easy. Riversmith's videos and instructions are spot-on and extremely helpful. The materials are top quality and I am very satisfied with the product for the price.
One minor issue I noticed is that the front mount does not lock and can rattle open. The one delivered doesn't have a positive catch to hold it in the "locked position." Overall, this is a great system, and I am sure I will appreciate its value over time when stream hopping.
