I thought I read in another thread someone had an aluminum cross member break a weld and the floor started to squeak and sag when standing on it. My Sunset Trail has a squeak and "soft spot" in the hallway. I haven't been ambitious enough to pull the weather guards off the bottom of the trailer and inspect it myself, but that seems like the culprit to me.
Hopefully someone else has experience with this. I'm curious too.
