Is this cold call acceptable, marginal, or terrible

[blackize]

Yes this hand is misrepresentative of the SB's actions in other hands.

The average pot size is 10BB's, but as I stated could pretty easily be forced up to 20 if people weren't afraid of the maniac. I was confident that I could push the pot up to 20BBs anytime I had a hand.

You are right that I left a few bets on the table. I should have definitely raised the turn and maybe even the flop.
