Any body have this issue or any thoughts on it???

Hmmm....I'm not so sure about this theory. Even if a vacuum force were created, which I'm not seeing how that would happen exactly, there are so many leaks in the TM that I don't see how it could ever build up to create negative pressure. I suppose it could just blow in, and maybe even very small amounts could be easily detectable.
I think I would give Suburban a call and talk with tech support. Absent the gas coming in the door or window, I too am confused as to why you would be smelling propane with a sealed combustion chamber. Even if your vacuum theory is right, how do you fix it? And if that's the problem, why doesn't everyone with a blowing furnace have this problem?
Also, propane is odorless. What you are smelling is an odorant, probably mercaptan. I'm not sure if that has any relevance here, since its sole purpose is to alert you to the presence of propane, but I have read that mercaptan can be absorbed into certain materials (like tank linings, pipes, masonry, etc.), so it sometimes can be detected in the absence of propane (although I seriously doubt that here).
