Choosing A Refrigerated Delivery Option

I recently helped a friend send fresh food products to another state, and we were concerned about keeping everything cold throughout the trip. While comparing options, I started looking into refrigerated truck delivery service providers and learned that temperature monitoring, loading time, route planning, and truck condition can all matter. We wanted to make sure the shipment arrived in good condition without unnecessary delays. For anyone who has shipped refrigerated goods before, what do you usually check before choosing a delivery service? Any advice would be appreciated.
