So, you might have a type of cargo that you think should be in box/van type trailer. Maybe it seems appropriate to you. But the reality it might need to be on a flatbed, or hauled in a reefer.
Obviously there are times, such as transporting rare ancient artifacts, where you are the best one to oversee the shipping and handling. But under normal circumstances the carriers do this for a living.
There is no reason what so ever for you to dictate to them how to best perform their job.
If this is truly the case and you don’t feel comfortable with them and feel the transportation liability risk is too great, don’t use them.
There are literally hundreds of trucking companies from all over the USA. Missouri, Nevada, Oregon, Florida, every state has so many to choose from! Many even specialize, so all you have to is research a little on trucker forums and magazines, and keep the transportation liability risk to a bare minimum.
