Yup apparently his minivan was not running properly.
To the OPs question, I may have missed where he stated miles, condtion, repairs done.
There are some 10-15 year old vehicles I’d take anywhere and some that won’t make it across the street and we interweb users have no idea of the actual condtion of the rig.
As designed, the truck will have no issue with it. I don’t even recall any real grades from the Midwest to the East gate of Yellowstone, but my truck eats 6 and 8% grades for breakfast, so not too cognizant of what’s out there.
