I recently purchased a 2014 Ram 4x4,ED Laramie. I traded in my 2009 Ram Big Horn SLT with 182,000 miles on it. so far the fuel mileage is on track and bells and whistles are handy. I'm a traveling salesman and can't help but notcie the stiff ride.It often feels like a 3/4 or 1 ton ride. it does not have air suspension. is there anything that can be adjusted? anybody else notice the stiffness??
