Like Richard, I saw nothing in the photos that would concern me. Starting with 2006, all of the Newells I have looked at with the larger windows have had seal problems and have fogged. Expensive to repair but since five have already been repaired, the remaining two may not be too expensive. The serious issue may be the slide seal and the unit may have to go back to Newell for an expensive repair. When the unit is plugged into outside power, the inverter does not charge the chassis batteries, only the house batteries. Most of us have chased water leaks through the windows or roof and not a big deal to seal them. Good luck in your pursuit.
