We have a 2004 28ft CCD and a 1995 21ft
Sovereign We use the 28 for longer stays and the room the 21 is used for week-ends and short trips ,They dont make the 21 any more and they dont make them like they used to The 21 has tamden wheels which makes it a dream to tow and manuver.Its not wide and you dont have to worry about it not tracking true. It has the same holdings tanks as the 31ft And the shower is larger than most Airstreams The bed is cozy. Want to know which one we use the most ?? Quick to hook up and go and i believe they are much better than the single axil Bambies.. Keep the 21 if you can!! and if not anybody looking for a small unit needs to jump on this one JUST MY OPINION!!! BILL
