I found a used 2020 TK1 for sale about a month ago. Technically, it's used but the owner bought it brand new in May 2020. It has the chock and the spare tire/mount. He also had the dealer add an aluminum rail that goes across the trailer at the ramp. He wanted this so in case his TG came loose it wouldn't roll off the back of the trailer. He wanted $3200 for it so I bought it. I have since added 2 5-foot sections of E-Track on each side to provide for more strapping down options should I haul something other than my TG or a different bike. Very impressed with the trailer and glad I found one. I haven't seen many, if at all, for sale used and local dealers in my area don't know when they will have them in stock.
