Gerald's right. I remember somewhere before 2004 when we started looking for a new rig, major mfrs. like Country Coach and Monaco, and Freightliner coach users like Newmar and Tiffin, started bigtime touting 55 degree max wheel angle. Put that together with our shorter coach (36' 10"), and maneuverability is relatively easy. Seems like later there was talk of some rigs at 57 degrees.
