Well, there are reasons to store jacks down.. however a Chuck implied, there is no reason from the jack's point of view save if they are FULLY extended. that is the only time I'd worry if they are at MAXIMUM extension

When the jacks are up. there is no pressure on the system. when they are down there is constant thousands of pounds of pressure on the system, since you are supporting part of the weight of the chassis. Sounds like pressure on the valves, hoses,etc. OK I'll put them down. I have HWH's..

Every manual I've ever read (and I read them all) says to park with the jacks down, take the weight off the suspension and tires. Personally, I would ignore the answers from trailer owners, as they just don't apply.
I store my rig indoors with the slides out so of course I have the jacks down. I do run the slides in and jacks up at least once a month. That seems to be the useage schedule. Have had not problems at all.

If the sun heats thigns up and the hydraulic fluid expands a bit there is some room for expansion in the jacks so the pressure will not go out of bounds.. Likewise if it cools and contracts.
No, I don't see as that's hard on the system at all
Now leaving it with the pump running.. NOT GOOD but you never do that
You would have to be parked on the darkside of the moon to worry about temperature changes in hydraulic fluid and expansion. It just doesn't happen on a static system. It would be a guess, but I would have to say it would take a couple hundred degree or more change in temperature for hydraulic fluid to expand or contract if at all. You are perfectly safe parking jacks down.
