Wall test for DB-Drag?

[groundpound4200 5,000+ posts]

I was reading the rules for the divisions and I have a question about the wall test. The wording is really strange and there is no illustrations. Can anyone explain this better before I start cutting my box. Does the box have to be below the lowest window line in the cargo area for an SUV?

thanks

No one knows what constitutes a wall for DB-Drag?
