I lived the idea for a ventless dryer but there was a lot of condensation. The bottom right corner began to rust after a few weeks due to condensation. We emptied the tank after every load. The tank is in the upper left corner of the dryer so we feel it was unrelated to the tank. The dryer was level. Online help said to tilt it slightly to fix the issue but that did not help. Also takes a long time to dry clothes.
