Got some measurements off of Dark Aero's belly pan to calculate the exit angle. 
Length of belly from the end of the diffuser to the end of Dark Aero = 76"
Distance from ground to the bottom of Dark Aero end = 16"
Exit angle from the rear diffuser to the end of Dark Aero = 3.95 degrees.
Overall length = 288".

Rear diffuser lost the bolts on the right front hinge and was flapping a little bit on the way home. I guess it screwed up my numbers a bit. 
Got the bolts replaced and bolted the hinge back in. A quick run into Houston in the afternoon was indicating around 25mpg on the Ultragauge.

Did you use Nylock or split washers this time?

I had split lock washers on the bolts last time. I've decided to use some thread locker this time.

Finally had some time to cover up the crossbeams with the rubber baseboard strips. Zip tied them to the slotted angle about every 8" or so on both angles fer both beams. I'll have to make a run and see if it makes a difference or not.

During my 2017 Christmas run up North to Nebraska, I ended up in some serious snow which built up between my main belly pan and the floor boards. The snow didn't even melt when I zipped down to Arkansas fer a few days and I had to remove my side skirts so I could dig it out. Maybe I should configure a winter/summer mode due to the amount of snow that was built up between the belly pan and floor boards with the summer mode sealed up and the winter mode opened up.
I was over rough terrain fer the few days and ended up taking some damage to my rear Coroplast vertical skirt bottom gap covers. I noticed that lower part of right side vertical panel had broken free at the rear and was dragging on the road. I was wondering if having both of the rear vertical skirts dragging on the ground would make any significant difference in sealing off the turbulant air coming off of the rear tires and setting the rear diffuser with cleaner air. The new rear skirts would pivot near the rear axle and contact the road at the rear with a possible option to retract them up when backing up or only using them fer highway use. This would make them a replaceable wear item.

An L shape 1 vortex diameter above the ground is what LeMans cars are doing for their diffusers the vortex (with proper engendering) will act as a solid .
https://www.youtube.com/user/Kyleengineers has a video explaining what I'm trying to say I was not able to find it quickly this morning work to do so I don't have time to dig at the moment
