This rig was built on the 38/40 foot chassis that was shortened to 32 feet as a proto type. One of it's kind! Handles like a large PU truck. Turns quite sharp for a class A RV. The 8.3 Cummins and 6 speed Allison transmission are a great match. 9-13 MPG at highway speeds. A little small for full time living but manageable.
