i currently have a 2001 srw and i tow a enclosed car trailer(30ft. ) which weight about 10000lbs. i was considering upgrading trucks to a drw for the safety factor at highway speed. currently i have some sway and i really have to pay attention to trucks as they pass me so they dont suck me in. i have never towed with a dually and was wondering if it is worth the effort of converting mine with some arrowcraft fenders and spacers, or just sell it and get a new truck. not only that but, will a dually really make that much of a difference from my single?? thanks, please include any info you may have on arrowcraft kits.
