We had the popping and cracking sound last winter in FL. I did the fluid replacement per LCI, but that did not seem to help. My rig, Coachman 2012 Encounter, was parked in full sun. The past 3 weeks we were in Maine, parked in the shade, with 1 or 2 minor cracks/pops. Seems like the noise last winter may be expansion in the jack lines? Will be camping for the month of Sept. in NH, will post if popping/cracking returns.
