Parked covered or uncovered? Do you have the covered or uncovered vents? How's the wind there? I know the heat and sun are brutal there but not sure of the wind.
The cons of course are everything plastic that the sun hits, including your faux leather furniture, will over time get brittle and break easily. Wood will shrink. Fabrics will fade. Stuff on the roof like the shower skylight will get brittle too. For the interior, get sheets of that reflective bubble wrap to put in the windows. But you need to have the vents open to help keep the interior in better condition.
If you can find it, you'd want covered parking. Vents should be opened all the time if they're the covered type, or if not but you're protected from the wind or rain, or if you can drive over real quickly and close them when necessary.
Other things would be disconnect the batteries negative leads, fill the fuel tank shortly before parking, check all fluids. Drop the jacks to just take a little pressure off the tires, maybe park the tires on wooden or plastic boards.
