Yes you can, but should you. A lot depends on it, I would say no if in a sea air e nviorment. Also even when I was in Florida this year for 2.5 months, yes they stayed deployed, but once a month a wiped the rams down and exercised them, only took a few minutes to do. Wipe them down , pull the slides in and retract the jacks. Hit auto level relevel and put the slides back out, maybe 15 min job. But I don't want them pitted or the seals to dry out, that's just me...
