The reinforcement strips did their job on the trip back home. I ended up putting them on the outside. The gap cover never did pop up once on the return trip like it did a few times during this trip out to Kansas.
With the rain down here in Houston, there hasn't been any rain gitting past the gap cover seal. I think this setup is a winner!
MPG was consistently around 25mpg coming back to Houston vs around 22-24mpg during my previous trips. Sorry I didn't git a chance to see you this time around, aerohead...had to pick up a full roll of CommercialWrap Tyvek in Allen fer my cab cover trials. I'm sure you would've liked to have seen the gap cover/access doors in person.
Since the roll of Tyvek was 10' long, I had to open up the rear sliding window so I could fit it inside the truck. Amazingly...there was barely any wind noise and no backdraft of exhaust gasses were coming into the cab.
