Corrected total weight V1.0

With the trailer fill limit activated, some devices cannot be filled correctly for field work because the permissible total weight is configured for road travel instead of for field use. This mod adds an additional shop object with a corrected permissible total weight for field use for the corresponding vanilla devices. The following devices have been corrected/improved: Annaburger AW 22.16: 28 t Bergmann TSW 6240: 28 t Hawe DST 16: 20 t Lode King Distinction: 50 t Samson US 235: 35 t Oxbo BP 2140: 34 t
