Still going through my dilemma of deciding which tow rig to buy. While I would love a GMC 3500 Crew Cab Dually, that's a big freaking truck for daily driving around town. I am also considering the SWB 2500HD Crew Cab. But, I have a question. I am expecting to tow the Jimmy on a gooseneck trailer. I will also be replacing my small travel trailer with a 5th wheel trailer in the next few years. Should I be concerned with pulling a gooseneck or a 5th wheel with a SWB truck? Can I do this setup and still have a toolbox mounted at the front of the bed? Or am I going to have clearance issues?
