Midlands Carrier Transicold in Omaha, NE. Ask for Zac. I paid $5,500 for an Ultima 53 in 2013 (installed) with 10k hours. And last year he quoted me $6,000 for 2100A or 2500A, but all he had were 12k hours at lowest. I waited and then just bought a new/used trl when the bottom fell out of the market. MCT has a big railroad contract and have I guess 50-100 just sitting in their lot.
