Moab Utah to Salt Lake City Utah

6 is a good highway - no bad grades or anything.

Yes, we've driven it many times. There are some up and down, but nothing major. Soldier Summit is a gradual climb as is over the Price area, but again, nothing major. It's a good road.

This may help you too - Mile by Mile Hwy 6

it is the main route for cars,trucks and rv's of all sizes and shapes you shouldn't have any trouble.

Not only is it a good road and not too challenging, it's a pretty ride. Go for it!

I've developed a dislike for hwy 6 over the years, but that is because I seem to always hit snow towing the toys back from my winter excursions from the SLC area to Moab. It's a major highway, one minor uphill climb of maybe up to 6 percent grade coming out of helper for a few miles but nothing that has ever been a problem even when I've towed doubles with an underpowered truck. You'll have a lot of RV traffic going the same direction as you take that road on a Sunday, with a goodly number of boats returning from lake powell.

Thanks everyone for the good info!
