didnt know about that pack where did you find it? use the hooklift I have its a longer frame and AR will attach in any configuration the hooklift or fifthwheel will dissapear when you connect to ar just have racks aloud turned off that was for the Phiber x2 so it makes it look like it has a front. the hooklift is stretched as far as possible at this point. The hooklift has so many hidden features I need a video to show but videos are always too big to upload or quality has to be so bad you cant see clear
