Sorry about hijacking the thread but it seems like a good place to be discussing this stuff.
I had another (probably harebrained) idea.
On some motorcycle windshields you can get a vent to bleed some air into the low pressure area behind the windshield.
Go get some of that flexible tubing that they use for heat and air conditioning ducts. Cut a couple holes in the front of your trailer. I'm thinking at the top ourside corners, but there might be a better placement. Hook the flexible vent up to those holes and run it along the top inside corners of the trailer. Cut a couple holes in the back of the trailer and hook the flexible vent up to that.
Now when you're running down the road it'll bleed off some of that air pushing on the front of the trailer and send it right out the back to lessen the suction on the back of the trailer.
Just a quick idea. Maybe there's a better placement for the intakes and outlets.
