Interstate Cold Storage has expanded its delivery capability by adding two Glacier King - 20 freezer vans to its fleet. These freezer vans are built on a Sprinter Van chassis, which offers an excellent solution to hot shot runs or special orders. “Scott Parker said, insulated freezer vans allow us to keep our larger semi-trucks on the road, while supporting additional customer needs in a more cost effective manner. Being able to pull-up curb side for a delivery opens up a whole new level of service for us and at more than 18mpg, we just can't go wrong. “The Glacier King - 20 offers temperatures down to -20 degrees and is available for emergency deliveries until 5:00pm within a specific mile radios.
