A 2-foot fiberglass H Flume in the bed of a pickup truck.  The 2-foot H Flume is as large a H Flume as can be transported (with an approach section) without a trailer.  

Here we've loaded up the flume for courier service to the University of Kentucky - Kentucky Geological Survey. The client had an urgent need for an H Flume as part of a cover crop study.  From the time of call to delivery at the customer's site, less than 48  hours passed!
