No. For in the mountains You gain back, up to about %25 what you use going up and going up you use 2x-3x what you do on flat ground. When I drive to Fish the resurrection I go over 3 passes. And in my 3 average 25-30% more then I use driving on flat. Towing will be similar. My bet is Up and down (like you mentioned) you will use 30-50% more than on flat ground.Can you make up the majority of the range that you lost going uphill on the downhill side? Towing through West Virginia and picking up range on the Downhill side would be amazing. Same with I 24 going through Tennessee.
