Earlier this month, Trainworx announced that it will re-release its 53' trailers. These trailers will be available at the same time as the company's new Freightliner Cascadia tractors (very popular modern class 8 tractor).
Pre-orders for these trailers are due by November 30, 2017 with an estimated summer 2018 delivery.
These trailers will run $23.95 and come in 5 versions: Xtra reefer, Xtra dry van, Xtra dry van with skirting, Hyundai dry van and Wabash reefer. The two reefer units will feature a detailed exterior-mounted refrigeration unit at the front end of the van.
Here is the original announcement.
