Travel mode = the coach is sitting at the correct ride height. If the ground is unlevel, the coach will follow the ground. Also deploy and retract slides in travel mode. Always!

Level mode = ability to inflate or deflate air bags to level coach with the horizon. The coach will not likely be at correct travel height when in level mode. Do not extend or retract slides in level mode. In level mode it is very possible to induce a twist in the coach frame which can bind the slideouts
