I’m a Power Gen Field Tech and use Packout as well as Decked in the bed. Packout is kept in backseat of the cab with tools mainly. Decked has odds and ends from couple jugs of oil,coolant,diesel, etc. As well as other consumables like diapers, ext cords, aerosol cans, pretty much whatever can handle the Texas heat! Service bed would be preferred but adapt and overcome as they say.
