I am not really new here to the site but I am posting for the first time. So, I will start off by introducing myself. My name is Rob and the tow rig is a 2006 Dodge crew cab Cummins. I have a 3500, long bed dually, that is silver in color. Last week I lifted the truck with a Superlift two inch kit that lifted the front around three inches. No spacers for this rig. This Cummins does pulling duty for everything from small 20' flat beds to pulling our tandem dual back-hoe trailer and then a camper behind it. For Moab this Easter we pulled both trailers at once, about 15,000 lbs. I hope to do more learning here from the site and I hope that I may have some information for other users as well. Catch ya'll later. Rob Knoell
