How bad does this look to you?

Is this gap large enough to be concerned? The wall is solid.

If it wasn't there before and now it is....I think I'd be a little concerned. That is a pretty wide gap.

Do you use your shower? If so, I would think a good bit of moisture could get in there.

Mine has sealant in that location. May have been missed. Wait for the dealer or do yourself.

No indication of what RV make this is. It appears the walls were cut short. I think it needs to be repaired properly, wall rebuilt and caulked. That gap will be a mold haven.

It is a 2014 Flagstaff 8524.

My first thought is sagging floor.... but it is pretty even for that condition.
I then assume Deuce is right with “made that way”.
