The access doors didn't flap at all like they did before. I've been doing some clean up on the aero cap and added in some rigid supports on the hinge. The bungee cord was pulling the aero cap sides in and creating a gap between the trailing edge of the access doors and the sides. The new added supports pushes the sides back out where they are supposed to be and closes that gap back up. Moved the swivel interior lights to the hatch main rails so they aren't obstructing the rear view as much as they were...
Got in late last night and didn't git a chance to refuel...but the Ultragauge was indicating close to 29mpg from Topeka to Wichita...but I was experimenting at 55mph cruise vs my normal 65mph cruising speed. I figure fer a 2 hour trip I wouldn't lose too much time fer such a short trip. No way would I cruise at 55mph fer the whole trip home...at least fer now. Fergot to mention that my gas mileage going to Topeka from Wichita was around 25.5mpg at 65mph.
The 33% grill block didn't cause any probs with the alternator temp (about 4°F above the engine bay temp). Might move back to my 67% grill block before I head towards home this coming weekend.
