Hwy 64 from Cameron AZ to Tusayan AZ

Hwy 64 is no problem at all...good road.

I too always stop at Cameron. The Navajo Taco is superb. But mainly I enjoy chatting with the Navajo lady who is usually there working on a large rug on a massive loom. Her skills are amazing, and all the planning is in her head.

I've bought a couple of smaller rugs there -- wish I could afford the big room-sized ones!

Oh, and SR64 to Tusayan is just fine for any RV.

Agreed... Hwy 64 is a very good, scenic drive. We've done it with our 40' motorhome.

The Cameron Trading Post does have excellent food, especially the Navajo tacos. It also has a high quality gift shop, unlike some of the junk gift shops you find. It's on the right side of the highway.

Its a very good 2 lane road, no problem with your length.
The Cameron trading post has great food.
The little Colorado river gorge is a worthwhile stop with plenty of room for large rigs.
Enjoy the canyon.
