My spouse set up a living trust May, 2003. We were married May, 2009. He never revised the trust. My rights in Indiana?

There are three surviving sons and one deceased son whose children inherit under trust. I do not wish to take the real estate nor the investments. I only want the 2005 Ford Freestar and the checking account from date married, 5/31/2009 until his death 9/1/2014. Will this be a major problem for me since we were married after the trust was set up and there was no prenuptial signed? I would think I would be eligible.
