You'll need to measure the distance between the front landing gears to see if you're over 58" or not. With your rig, I'm assuming you'll need a kit that is for 58" and over. Now, once you have the kit, I'd think twice about having Camping World install it. Their service track record (from what I've seen) has not been good. You can also buy this same kit from Amazon as well, then take it to a respectable RV repair shop in your area to have it installed. Or, DIY!
Good luck and let us know how it turned out.
