I started a spreadsheet that lists all of the specs of the different models. I'm working backward from 2010. So far, it includes 2008-2010. You can search for "Boat Comparison Spreadsheet" to download it.
Meanwhile, the specs for '09 and '10 are:
Trailered width: 8'9"
Trailered height (without tower): 7'4"
Trailered height (tower folded): 7'6"
Trailered height (tower up): 10'10"
For '08, it shows the tower is not foldable.
