Something seems Fishy

My wife and I have our hearts set on a TM 2000 3124KS, Mr X is selling one and we have been trying to get in touch with him by phone for at least one week. I did some research and found a post by Mr.X on how unhappy they were with their TM because it took four people to close and latch it and nothing they tried seemed to work. I finally talked to him on the phone and asked if they had ever had any trouble opening or closing the Trailer. He stated never had a problem opening and closing it. I then asked about the water tank and then said well on the forum you said you had a problem and were very unhappy. He stated that it was just a simple adjustment and everything is fine now. What would you think?? I need to make a wise decision
