IMO the flapping is better than it was, but is still less than optimal. To me, the flapping would still disrupt the airflow to a certain degree.
My design has had no flapping in over 6 months of being attached. I used 1/4" aluminum bar for a bottom frame, and 90* tabs drilled into the fender as attachment points.
The tabs used. These are from Lowe's
I cut the coroplast to fit, and then painted black. Painting the coroplast helps it last longer when it is exposed to sunlight constantly.
They have been at speeds of up to and maybe past 80 mph with no signs of distress

I'll finish tightening the zip ties and take it for a test drive and hopefully return with it still attached.

Zip ties will work. I have had my front and rear pans zip tied for around 6 months and they have held up great. Just make sure they are tight! Pic for reference.

I'm thinking of having the front piece rest on the bottom lip of the bumper so it can't get the parachute effect going if the front zip ties break.
|
Exactly what I did. I drilled a screw into the bottom of the front bumper through the coroplast, angled up towards the radiator. I have it rigged in such a way that when I tighten the zip ties down, it pulls and holds the coroplast down on this screw. The duct tape is no longer there FYI

I'm going to see about attaching smooth wheel covers to the center caps. Would a kammback on the back of the cab be helpful or would it hurt the existing air bubble that's formed in the bed? Kammback would be easier than a full aero cap to collapse and store for towing.

Phil (aerohead) has data showing that a 2/3 bed cover (open space at the front) is a better choice than a full cover and it is much easier to design than a kammback. If it proves itself, you could remake a more permanent version that folds up and stores away in your bed for the instances you tow with your 5-th wheel. Easy on, easy off
