Have the 2011 6.7 and love it too, adding this 2013 and remving a E250 as a service van, it just became too small and crowded, the 2013 will have a full service body 8" with 51" covered top with the two vertical doors, (walk in type)
the 2011 also has a service body 7' with sliding lockable top. Had that body on 1999, 2001, 2003, 2006, 2008 and now the 2011.
My RV is a Foretravel with the Cummins ISM500 @ 1550 torque.
Also been into ham radio since 1957, CW hound mostly, 50++WPM is best.
