Need some help choosing these, i was going to go with the F450 dually diesel and get a gooseneck i heard its easier to drive with the gooseneck. What are you guys currently driving + trailer? I am getting a kubuto 97-3 so it will be heavy, im trying to avoid the cdl route. Does that mean i have to regrade the trailer? I think ill be at about 15k lbs with the mulcher head and tractor.
