I have an SV-291 as well.
Watch the front storage doors as both of mine leaked with moderate rain. I am going to change the weather stripping myself as FR was of absolutely no help (I imported it to Canada from US). They would not even send the weather stripping claiming they had no idea what I was talking about. So I paid 40 dollars for it through my local dealer.
The clock support across from the microwave has sharp screws protruding inside the cabinet, be careful, as it will easily make your hands bleed if you touch them.
The TV stand has loose screws on the upper rotator and they will come off one by one.
Check the incoming water filter next to the water pump, mine was loose and my trailer's washroom got flooded first time I used city water.
The lower bunk bed is not supported properly on the pack and play door side, check it otherwise it will just fall down in the middle when someone gets onto it.
Other then these it is a fine trailer, I like the floor plan. I wish I had purchased something else though. Especially the water leak is ticking me off
Good luck with yours.
