That's if you run the heater...
Though I can't imaging a happy wife doing that... lol. Time to get some Canada Goose then lol.
We don't go on too many long vacations (maybe 1/year) that would cause us to stop a couple more times in a 75d vs 100d so that is my rationalization. Also, if we go on a long vacation when it's more mild/warm, we'll have closer to 200 miles anyway. It's just the winter that has me crunching numbers.
Another thing I'm taking into consideration is the launch of the Model 3. I see 2 sides to this...
1.) There will be more superchargers getting stood up.
2.) There will be more Model 3's using them.
I guess it depends on the ratio of both and how many people will be traveling when we do.
