@freebeard thanks for the suggestions and I've been looking into the airtabs or diffusers. The airtabs are a bit unattractive but we may opt for the smaller roof top diffusers.

As for the speed issues, Yes for 3 years the van struggles to go 80MPH through a 75MPGH zone. But after remove 10 of the 14 slats and for the first time, the van reached a top speed of 110MPH. Nothing's change and driving on a flat straightway.

1 weeks has now passed and the van MPG's is holding steady at 24.0
