I came across your posts on Irv2 and the Thor Forum. I have a 2014 Thor Four Winds 34SW Super C and have had very similar problems to you. Purchased in February and has now been back for service twice amounting to ten weeks all together. The last time it was in was for the slide issue, the same as you apparently had, and also because the automatic leveling jacks blew out. Apparently the connections on the hydraulic lines have some plastic fittings that are weak and are known to fail. I am curious about how your slides are working since you had them fixed. it seems like both of our experience is quite similar. I would love to change notes with you but would rather have a private conversation if at all possible, I can be reached at email@example.com. My name is Scot Harden and I live in Menifee, Ca. I certainly hope that all your problems are behind you. Thank you for your time. Hope to hear from you.
