From Dallas to Las Vegas, need advice?!

It looks like the Suburban is under their "Premium" SUV category. Chances are you'll get something along the lines of the RAV-4, CR-V, Escape, Liberty, or Equinox.

It certainly won't be a suburban, unless it's an upgrade.

Of course there is an obvious answer to your question: Call them!

If you actually call the rental location at DFW {(972) 453-4500} they should be able to tell you what models they typically have in their fleet.

The 1-800 number, national call center, won't be of much help but if you talk to a real person at the actual location you should get a good idea of what you can expect.

Also, please look at your previous post, as asking the same question multiple times is rude behavior that we would prefer not to see again.
