Goody gravy!!! That's nearly 10 inches of total lift! You'll have a hard enough time keeping the shiny side up even without anything in tow. Time to accept reality and find yourself a decent, older 3/4 ton pickup or suburban type vehicle that's already setup for towing loads much heavier than your boat from the factory. Resign your Scout to trail pig/mall cruiser duty and enjoy it for what it is...a fun in the sun, non-towing vehicle. This isn't a time to try and prove the naysayers wrong.
