What is the quality of Dongfeng Tianjin Songchuan refrigerated truck 6.75 meters? Please advise.

The carriage was average, and the price was relatively cheap at that time. The main domestic refrigerated truck box factories: Henan Hongyu, Xinfei, Xiong Bing, Zhenjiang Feichi, ConocoPhillips, Shandong CIMC, Anhui Zhonghang Le Kai, Hefei Jianghuai, mainly these domestic manufacturers have done a good job in quality. There are many brands of refrigeration units, but the quality is different and the price is different. Zhengzhou Xue Kai refrigeration unit is good in domestic units and can be considered as a listed company.
