What was the front end caster set at? Should be > 5 degrees for best highway speed handling. IMO
X2 That would be the first thing I would check. Get your coach weighed loaded as you normally travel and then take serious look at your tire pressure. As far as the movement you are feeling when the big trucks blow by there is nothing wrong. They are 80,000# going 75 or 80, trust me there will always be a serious "bow wave" of wind and it will move you. Keep one eye in that outside mirror as there is usually a lot more surprise than actual movement generated.
I doubt a new E-350 needs any additional equipment to provide a smooth and steady ride. If it did Ford would have done so. Our 2012 E-350 drives and rides just fine but we are well under our weight limits, properly balanced, with the correct psi, all of which make a huge difference. :C
