Recently my wife and I started noticing a smell under the sink when we open the cabinet. It smells just like the release vent outside. Should I be worried? Once it was pretty bad, I checked both vents outside clean as a whistle. Also, Could a vent on top of the TT be the cause. We are a little concerned.

Are you smelling a sewer smell or a rotten egg propane smell?

If it's a sewer smell, look for the air admittance valve, a round plastic gizmo roughly the size of a baby food jar stuck on the top of the sewer line. It probably needs replacement. They're readily available at hardware or home improvement stores and not very expensive.

If it's a propane smell, you have a propane leak and that should be taken care of ASAP. Maybe a stove burner isn't turned off all the way, or the oven pilot isn't staying lit, or there's a leaky line or fitting....

My guess is the air admittance valve.
