Check Tahoe model?

[BoatDrinksQ5]

A couple things have seemed odd to me about my boat and I somewhat question the model year. Is that posted anywhere in the boat?

Oddities:
I was able to put 20 gallons in and dealer already had put a gallon or two in....that's well above tanks rated value in 2012.
Engine says 2010.... (i suppose they use old stock...especially to bypass EPA issues)
Trailer doesn't seem as short as it should be...(2012 it's shorter then 2011...)

Check the HIN on the upper starboard side of the transom. . . the last 2 digits are the model year.
