@shineybullet - it was pinched when I bought it. My guess is after the door sprang, it was letting in water, and this was their solution. We unpinched it, and it looks worse than if we would have left it!!!
I had a bumper that was taken off, and had to be put back on...a 3" canyon cut out of one of the main support beams to make room for 4" residential plumbing that obviously doesn't fit...so they had to jerry rig it under the belly pan (that was also cut to shreds).
I am guessing that it was a tiny house for grandma and grandpa in someone's back yard, and the person "fixing" the trailer knew enough to be dangerous, but not enough to actually fix anything :/
