http://board.marlincrawler.com/index.php?topic=11671.msg572273#msg572273So the first version only lasted 1 Rubicon trip and the second version has lasted now 5-1/2 years of a lot of wheeling, daily driving, mountain road driving, and long highway driving. They are certainly not mainstream and have their own quirks about them. They have survived 1 trip through the Rubicon with a trailer as well as one trip into Thompson Lake at Dusy/Ershim with a trailer.
I love em!
