To bring the topic back on track...
I received my trailer back today from FR. The repair was done beautifully. We also had them repair damage that I did to the trailer during backing. Everything is great. They also repaired some things that we did with the slide out. They replaced my tires and my bearings with no issues. I'm glad to get my trailer back, and I'm definitely glad that they took care of this. It does still whistle, but we know how to fix that now.
I will start working on the jacks, but I think I may end up replacing with scissors instead if I can't reinforce the jacks to work properly. I'll post/notify my findings.
