The unit could be in either cool or warm mode, remember reefers do both. Without knowing what is in that truck there is no way to give a better answer.
It would not be limited to vans. Ive destructed 15K store inventory on a few feet of overhang with a botched escape attempt. The problem is the space is 50 feet, century took 44 of that. Trailer overhang was 12 behind tandems. Boom. They did not fire us because that fiasco was on the store manager who sat in his ivory tower failing to deploy staff to manage traffic so we can finish delivery and get out.
Their back up cammera broke and the cheapskate company is to cheap to fix it. How else are you supposed to see something behind your trailer? Duh. Lmao
