Interesting trailer adaptation.
Similarly designed equipment is moving on certain lanes in the lower 48, but primarily for non-regulated, therefore non-pressure equipment. Quality Carriers and Schneider National are marketing the service. Looked at as an alternative to isotanks that have lower payload and require higher clearances for loading at many shipper racks.
Where I work, we've been running loads with this equipment out of western Michigan to the Piedmont area with a dray to Chicago and NS move to destination ramp.
