I also rented one of these for a one way trip Texas to Nevada. 20 miles west of Albuquerque the rear right tire went flat. No problem, easy to change a tire.
I start looking in the rear cargo space for the spare, jack, and tools, not there. So I break out the manual. It says the spare tire, a donut, is located up under the passenger compartment between the front seats.
The lowering device for the spare is in the console between the front seats. What a pain so far. I am down on the ground looking under the vehicle for the spare.
I found the empty space where the spare should have been.
Back to the manual. Found that a spare tire is optional and that the vehicle may or may not have a spare tire. If no spare then an air pump and fix a flat can are included.
Found these, put the fix a flat stuff into the tire, waited the specified time then aired it up.
Tire aired up to normal pressure, disconnected the air pump and the fix a flat stuff is leaking out of the tire and the tire is deflating.
The hole in the tire is too big for the fix a flat stuff.
Just something to check if you are buying one of these.
There is not much 20 miles west of Albuquerque in I-40. Cell service was spotty. Enterprise rent a car was useless. Get the vehicle to Albuquerque and they will swap it out.
Left on our own to get it back to Albuquerque. At least it is late fall and temperatures are not extreme.
