The original subframe of the THW (German Federal Agency for Technical Relief) body needs to be reinforced. For this, I welded three crosses from 60 mm x 60 mm square tubing, 4 mm thick. I then welded these crosses between the two struts of the subframe to prevent it from moving and damaging the cabin. All other additional reinforcements visible in the picture are only intended to support the floor panel and secure the storage boxes.
