I have AC too but we're in CO and there are basically no electric sites here. But it's low humidity and cool at night so it's mostly unused.

I haven't tried the hose extension because we haven't had tent room.

This is our porta potty tent. Works fine but can be finicky to collapse to put away

We always use RV toilet paper so it dissolves and makes dumping the potty easier.
