I agree with everything Netjam said.
I have a Nexus Ghost. This is built on the International Durastar chassis. The only thing I dislike about my Ghost is the wind noise. I have attempted everything to reduce it to no avail. The new Ghosts are built on the upgraded MV chassis which uses a single mount for the mirrors. It may be that turbulance around the upper mirror bracket is causing my problems. Perhaps the new Nexus units do not have the problem?
Because the diesel engine is in the front you do hear a lot of engine noise particularly when the engine brake is activated or the transmission downshifts. I have found running in economy mode (transmission) with the cruise control helps a lot.
It does handle great once I weighed it and reduced the tire pressures. My wife does drive from rest area with no problem and since it is 25,999# a Class B license is not reguired. She was reluctant to drive a Class A but never did actually drive one.
There is limited pass through storage over the drive shaft which works great for long items less that 8" thick.
We average about 9.0 mpg towing a full size SUV and about 9.5 mpg without tow. 23,000 miles so far. These things will tow up to 20,000# but we had ours built with a 10,000# hitch.
If you ever get close to me I would be happy to show you ours. We've done 2 west coast trips so far and are leaving in August for Alaska.
