Nothing on the roof (falcon wing doors and all that), but I had a full load of passengers, was sporting winter tires, and ran the heater the entire way. There was also heavy precipitation and wind. I wasn't exactly light on the accelerator. Left Kirkland at 100%, arrived at the top with 38%.
For the occasions when both L2 chargers are occupied at Steven's Pass, I carry a CHAdeMO adapter to get some juice at Sultan or Skykomish. At Steven's Pass there are 120v sockets on the back of the two chargers that you can trickle off. 5kWh might make the difference between needing to quick charge on the way back or not.
38% is plenty to get back down the Kirkland unless the battery gets cold soaked at the pass for a day. Precip will definitely increase drag and hurt your range. I've seen that drop mine 10% over what EV Trip Planner estimates on long trips. No precip and that site is dead on.
