I like this. Comparing these at around $5000 to a Habitat at around $10,000? I like it a lot.
Whatever fan used though I don't thinks that's the problem. It's where and how you choose to draw air in. The potential positive pressure the fan can create is not going to mean jack if the air intake is about to implode because a filter is clogged and no air is moving. Or if it needs cleaning so often that the fan is just turned off. Where do you place the intake? On the wall between the cab and the shell?
^^^^I'm not sure a Parker Pumper has the volume to pressurize an entire pick up shell. A better option might be a bilge blower fan for a boat, we used a couple of those on our Jeepspeed car to help keep the rear shocks cooled.
