It's probably just a preference...don't know that there is a right or wrong answer.

In my case - if I leave the slides out while parked at home, the roof gets filthy from nearby trees and birds and dust from the agriculture nearby (cutting their wheat last week kicks up lots of dust). Additionally some of the rubber wiper gaskets get a lot of exposure to the hot west sun...on the other hand if I leave them out the tires are protected and in the shade. I usually run our slides in after we are done unloading or working on a project inside.

On our previous RV (Laredo 330RL travel trailer) I felt like it was probably better to not leave them out because I hypothesized the stress on the cable slides might affect the longevity of the system. I have no proof my theory was right or wrong - it was just a thing with me. This was the first cable slide unit I had owned.
