6) With the VGs in place, they might act as an 'insurance policy' as far as flow attachment 'down' the whale tail is concerned. Since they're already in place, you might consider leaving them, at least until you make at least one test run, giving you 'data' for future comparison.

7) If the 24-inch extension causes the 'floor' to end right where the side panel's lower 'angled' intersection is, that would be great, taking maximum advantage of available pressure recovery.
Travel safe. Have fun!

Thanks Aerohead! I was hoping you would weigh in this morning. I will leave the VGs for now.
Are you saying the 24" extension should not have a floor? That would be easier although I do have a plan to install a large piece of coroplast as the floor from 48" - 72".
