Do you travel with your interior doors open or shut

We have a sliding door that we close and latch. Our bathroom door is closed. When it is very hot outside the heat in the bedroom will heat up the front of the MH, thus we keep it closed. We also run the gen when the outside temps. reach 80 degrees plus as our dogs in crates get warm and the dash AC will not keep the kitchen area cool enough so run the front Heat Pump on AC, works best for us.
