Non Emergent General Questions

As I get back to Pod Piddling I can't help but to think of more questions for you experienced Podders.

1. I noticed on our last outing here in the deep south it gets hot. I noticed when we ran the AC along with the Microwave and TV or Water Heater it would trip the breakers.
So...What items can you run when the AC is on? I'm sure I could figure it out but I know y'all know already so I am being lazy.

2. When in storage mode, I "assume" it is best to store with the slide out in the closed position to minimize strain on the system. But does it really matter?
If left open does it strain the supports? Should supports be placed under the slide out to take some of the weight. ?

3. Can the mattress be washed or power washed and dried without the risk of creating mold. maybe throw it over a fence or something similar.   Is it foam or fiber inside. I would think foam could be washed , fiber would be a problem.

Thanks in advance
I am sure more questions will come to me.
