Our 2012 Nexus sits atop a 2011 E-350 chassis and is 101" wide. At 24' it is no problem to drive in the city, park in just about any lot or even parallel on the street. My wife noted that after three days of driving around Sun Valley Idaho that if I could get around that narrow/tight little town she could not imagine anyplace else ever being a problem.
After 10,000 miles over the last 6 months I have no plans to change anything in terms of the ride and or handling. It is rock solid, steady, smooth and quiet (the new Michelin LTX M/S 2's run at 55 psi help in that regard). Windy days and passing semi's hold no terror and frankly it is just plain fun to drive. Our wheelbase is 159" with a GVWR of 11,500. We scaled out at 10,050 normally loaded in the middle of a trip leaving me an additional 1,450# of available payload (from our original 3,368#). I think these numbers explain why it rolls so smoothly.
