I'm roughly halfway in my drive from Vegas to DC w/my 2016 40e. I'm loaded to the gills with my wife, 2-small dogs, and a ton of stuff. Added to this is a Thule Terrapin hitch mounted carrier (clamshell thing) that's packed full too.

We've been driving with the suspension in "sport" mode as it wallows a bit too much otherwise. Tires aired up to max on the doorsill sticker.

We've faced "rare" weather with snow in Utah and Colorado the first two days. Summer Dunlops did fine in the slushy stuff and awesome in the wet, even with air temps in the low 30s.

We had favorable winds today which helped boost our overall mileage to >22mpg. I've run in Save Battery mode on the highway and then using the battery on the rest stop/gas station/hotel portions of the drive. No recharging of the battery on the drive so far.

Really happy with the way the 40e has performed. No issues at all on any of the mountain passes. It just pulled up the grades with all the power I wanted when I wanted it.

Taking it easy as far as the number of days to do the drive due to old dogs and no need to do marathon days.

Update: Now at a flat 24.0 mpg with an average speed of 71.3mph. Speedo error is about 2mph at 75mph according to Waze. Short day tomorrow will conclude the drive.

It seems to like the 93 octane gas I've been buying, though I think the slower speeds out east are the real reason the mpg's are going up. Certainly not moving along like we did when the roads were clear in NV, UT, CO, and KS.
