I made a simple tow bar that bolted over the front bumper and pulled my 6400 for 40 miles with a one ton 4x4 pickup ( chevy, of course) at about 50 mph with no problem. The truck tires held air but were bad or I could have gone faster. Make sure the tires are good, take a couple off the rear, disconnect the drive line, rig up some lights and go to it. That or get a goosneck trailer and load her up. A bumper pull tandem will handle the weightbut the problem becomes the distribution of the weight. Too much to the rear and the trailer will start to whip above about 45 mph.
