There is a good hill 15 miles north with a extra truck lane... maybe 1.5 miles long. Yes a gasser will probably downshift one gear... not a big deal. I sometimes stop at the exit just before to get fuel and since I'm headed towards Cleveland TN I'll take the old road along the river... no hill and a little shorter, but not faster.

I was going to say something but looked it up first. I was thinking the OP was referring to what turned out to be I59 South out of Chattanooga which has no long grade hills. Been on I24 a few times with some long grades but don't think we have ever used I75 before except in FLA heading for Tampa area from I10.... North Georgia HIGH COUNTRY has some good mtns there to cross for sure...

The only true "steep" out of Chattanooga is I24 up toward Nashville. I75 is no problem.

What type of coach?? Curious as to why you care...no disrepect intended but downshifting is a normal part of driving.
