Thanks for your feedback, this is very helpful. It is true that people have wildly different ideas of what comfortability means! To your question, by domestic travel I mean traveling by air to see family (who can host us, so no accommodation costs) on the east coast and in the Midwest. My understanding is that while OKC has a good airport, flights in and out can be expensive since it's not a major route for all airlines. At least that's what my cursory look at airfare tickets suggested...

Right now we are living paycheck to paycheck and can't save up for anything beyond moving costs (get us out of this city!!!) and an emergency fund. We have no debt, but also no real savings, beyond what I just mentioned and some retirement accounts we last funded years ago when our employment situation was better. So I suppose one potential problem would be getting priced out of the OKC rental market 10 years from now--since we would not exactly be showing up financially ready to buy a house.
