Original equipment in agricultural vehicle bodies is generally considered for mildew resistance prior to manufacturing. Therefore, mildew issues often arise due to prolonged use in humid climates, with the mildewed items typically being the contents of the agricultural vehicle bodies. As such, the agricultural vehicle body manufacturer advises that regular cleaning is necessary during prolonged use to prevent mildew and subsequent odor, which can contaminate the agricultural vehicle body.

Many people overlook the fact that they tend to pile up car washing tools and debris in the agricultural vehicle's bed, especially around the spare tire area, which is more prone to accumulating dirt and grime. The moisture that accumulates can easily flow into the grooves around the spare tire. Over time, if not used, the tools can rust, affecting the entire undercarriage. Therefore, it's important to avoid storing unnecessary items in the agricultural vehicle's bed.
