Maybe I got a lemon but it seems every time I turn around I am having another problem with my 2013 Sierra 365saq!! I got home from work last night it was 49 degrees out side. Well I noticed my trailer was shaking side to side. I go out and my landing gear is no longer supporting my trailer all the weight is on my stabilizer tripod!! I could move my block back and forth under my landing gear. This is fourth time I have had hydraulic problems!!! First landing gear failed then slides started walking out next cylinder went out and now this!!! Please someone tell me I am not the only one having problems with their Sierra. I have had several other issues too! I will never buy another forest river RV again!!
I'm going to guess that Lippert made your hydraulic components, and since they make those components for pretty much every manufacturer, I don't think you're going to see much improvement with other brands. But that's just my guess.
