You’re right, you most likely won’t need the AC in Yellowstone/Grand Teton, but if you anticipate needing to use generator power for AC later, I would give serious thought to buying two smaller parallel-able units rather than one larger.
I actually have a 3600 watt Generac LP unit built in to my TC, but I’ve found that the 1000 watt Yamaha is what I use 99% of the time. The generac only has about 125 hours on it and it’s 18 years old. Most 3KW or bigger units I’m familiar with are quite heavy.
