We store ours in travel mode with 110V compressor on. But, our floor is level. We just use level mode when staying in the coach. We have had a six pack valve get stuck a few times in level mode and 110V compressor can not keep up with air loss. We have to run engine compressor to overcome air loss & get six pack valve to seal. After that it is fine for quite a while. This is a very sporadic problem with our coach.
