Our 07 F53 rides like a loaded F550, exactly what it is. I drove everything from 350's to KW's when I worked, and it drives EXACTLY like our F550 stake back loaded for a days work...LOL. The ride isn't harsh, just stiff. I have Bilstein shocks on it and they seem to do a decent job with it. I have 0 upgrades done to the suspension and am comfortable driving 2 fingered most of the time. I would like to upgrade my swaybars though.
That being said, my 1990 F350 Dually, loaded with a 4,500lb truck camper and towing a loaded 2011 Ranger at 4,500lbs on a uhaul car trailer at 2,250lbs rode MUCH better. Got 9 mpg over 1,100 miles with the AC on.....lol.
