I bought a new Mountaineer in 2014 (2013 model). Went to the Rally in Goshen and had Tiara look at it, but they didn't have the right equipment. But they scheduled me in to Lippert the next morning at 7 a.m. Lippert just replaced the 2 big cylinders - told me it is usually the big ones that are bad. I am not sure they even checked to see. But mostly good - still creeped out on the way home but not much. Then dealer just cycled the slides in and out 8-10 times to get rid of any air in the lines and has worked fine up to this point (3 1/2 years).
Sooo. What is the warranty these days? If still covered in late summer, go to the rally and see if they can get them fixed. Well on second thought you probably want it fixed before then. Oh well. Good luck.
