As you can see the two trips were nearly identical for length and average speed. The major difference was towing the 130 lb trailer with batteries, etc.
The difference in energy consumption was entirely unexpected: it took an extra 4.9 Wh/km to tow the trailer. My original guess of an extra 1 Wh/km was so far off the mark that it is embarrassing.
Without even considering gravel impedance my range is reduced to 364 km and - using an additional factor of 1.5 Wh/km for gravel impedance - my range would be reduced to 340 km. This leaves me 65 km short of my destination. An even worse scenario is that my gravel impedance estimate might just as ridiculous as my trailer estimate.
This KOs the Dempster trip. Bummer.
Note: There is a plan "B" for the Yukon. I will write about it in the next couple of days.
