I purchased this vehicle (model: 231RK) in Roseville, CA in Dec. 2019.  I hauled it to my home in Yerington, NV where it has sat for the past 18 months.  It has never been used.  This is a very light weight unit that sleeps four comfortably and has an awning as well as a pop out.  The unit comes with a 2 year factory warranty that I assum is transferable.  Please call with questions (NO SOLICITORS) 916.770.6870.
Youtube has excellent videos showing the KZ model.
