I have a 2015 Great Dane Reefer with SB 240 Whisper Thermo King unit. Tire size is 22.5 with aluminum wheels on out side and steel on the in side. The unit has 10712 hours on it. Trailer is in great shape but does have one small kink on the passenger side from hitting the dock a little hard I assume. I have owned the trailer for just about a year now but looking to buy a drop deck trailer now. Price is $50,000.
