I'm in the market for a 5'er that has a GVWR of 16,600. I've pretty much decided on a 3500 crewcab long bed diesel dually for a tow vehicle. Most of the used trucks I see (GMC/Chev) have 4WD. Is ...
Having had both a IFS 2500 and solid axle F250, I find no difference in towing. I'd give a nudge to the IFS unloaded for a smoother ride but at the end of the day, they are both trucks and ride like such.
