Hello, My family and I would like to take a trip from Wisconsin to Yellowstone next summer with some stops along the way. I am towing a Wilderness 3150ds 35 foot travel trailer weighing in at about 8...
I've towed extensively through the mountains with my F150 the past 2 summers. As far as mountain towing mileage, I find it balances out pretty close to my usual towing mileage.
As for you concerns about range, I can't think of any main highway where you would have issues.
