Unless you known trucks and trailers the implementation of this procedure will be difficult. U need to get the details of chemicals use by the contractor to achieve sanitation, when it was applied and then inspect the interior of the truck and trailers for un wanted smell. it will not be easy.
If you own the truck & trailers then yes it is possible. One can use formulated chemicals which generates O3 (Ozone) to sanitised the interior . These chemicals do not generate any smell and effective for sanitation. H2O2 ( Hydrogen peroxide ) based product can also be use.
