Do you have to schlep the compressor out of the van/truck and roll it up to a connection point?
Most of the time I can pull up near it and run the skinny hose to the backflow. I have had to unload it only a couple of times. Next year we will have a tow behind. I have been running it at about 75 to 90 and sometimes I have to stop to let the compressor catch up PITA.
