Since mid 1040s plastics and RPs have been used in trucks and trailers. In use are long plastic floors, side panels, translucent roofs, aeronautical ovcr-thc-cabin structures, insulated refrigerated trucks, etc. (that were initially installed on Strick Trailers by DVR during the late 1940s). The lighter weight plastic products permitted trailers to carry heavier loads, conserve fuel, refrigerated trucks traveled longer distance (due to improved heat insulation), etc. Different plastics continued to be used in the different truck applications to meet static and dynamic loads that includes high vibration loads. Pickup trucks make use of 100 lb box containers using TPs and for the tougher requirements RPs are used.
