I’d start by checking your blocking/ground under the jacks, may be settling differentially under the weight if not on a concrete pad. If the jacks are leaking by internally sometimes you can hear them creaking. New unit I suppose could have a little air in the system but I would think you would see the issue prior to a few days if it was air. Next time it happens instead of releveling, just hit the rear jacks for a quick second to redistribute the weight and see if it improves. If it does, might be one or two of them having the ground settling under them. My 2 cents.
