RedRocket - thanks, I'll check out the videos when I get home from work. The TT is ducted (is that pretty much standard?) but I pulled the vents off on the first trip and was surprised to see that a lot of the tape had pulled away from the ceiling cut-outs and was starting to flip up and block the vents. That helped a little bit.
How are the ducts run? It seems to just be an air "gap" between two panels, not a "hose" or a duct.
I'm assuming this would also make adding a second unit almost impossible as I'd need to hack into the existing ducting. It's only 30a service anyways so I don't think a second unit is gonna fly, plus if I can keep things light I'd prefer it, though I suppose my portable is almost the same weight.
Getting a 15k is probably my best bet, however isn't that only a ~10% difference? It's a 2016 so I hate just throwing away a brand new 13.5k I guess I could eventually sell it.
ALSO thanks you EVERYONE for all the good ideas on tweaking the insulation, pillows, shades, etc. Again, I'm new to this so I have yet to learn tricks like that. This floorplan has a LOT of big windows in it for the size, so I'll need to figure that out. I definitely kept the blinds down though, and also definitely realized that even with a range hood / fan, using even one propane burner almost instantly made the AC useless.
For now I'll focus on better insulation of the AC, ducting, and the install of the unit - which as people said, is probably NOT the best in the business.
During the day I also point the two front-most vents (ones in the bedroom) away from the bedroom towards the main living space. The bedroom gets warm, but no ones ever in there during the day, well except the dog..
