I bought this RV as a new 2023 Thor Quantum MB24 . After a recall performed by Mercedez of Pleasanton , California ( after the VIN no. was punched on their computer ) , it shows as a 2021 Model year . How would I know if I was sold a pre - owned Motor Vehicle or a new one ? It has 2000+ miles in accordance to RECVAN @ Fremont , California , was acquired driven from Elkhart , Indiana to California . There were few issues and problems that I found out later after I had the RV parked outside my resident in Mountain House , California : Dirty outside compartment , Inoperable Navigation system , left outside wheel hub cap held by a single screw , all 4 rear wheel air valves not working properly , dream dinette can not turn to bed due to improper fit , some outside compartment latches loose , shower curtain had tiny slits , missing toilet bolt cover . Most of this issues was taken care of as part of the warranty . My concern is why is it a 2021 year model and not 2023 as per VIN NUMBER ? I s it Pre- Owned ? I don't have any way of knowing , hopefully you can help me with this issue . Thanks Respectfully , [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
