I leave mine out. It gives more shade to the tires in the Arizona sunshine.
Exactly........
The living room opposing slides completely cover/shade both curbside/roadside tires from sun.
PLUS we full timed for 7 yrs. and the slides where only retraced for 5 hrs. on travel days......rest of time they have been extended.
Side seals/wipers are still soft supple (baby powder 2X yr.)
Course 5vr is next to house and plugged in 24/7....emergency/guest house/man-cave etc.
OP---as to partial extending slides
NO!
They do not seal unless fully retracted or extended AND you should not use slide (stand on it/walk on it etc) when partially extended.
THey are self supporting when fully extended not in between position
