I just replaced my ENO DNsuspension system with whoopies and a marlin hitch tree hugger system. http://arrowheadequipment.webs.com/a...s/show/2575039
It took about 30mins from start to finish and that is because i watched the youtube video LD linked above 2 times before trying it. I did do the double pass through as shown in the video. Incredibly easy to manage.
