Seattle Wa. to 4 Corners mid to late Oct.

We are planning much the same trip for 2016 Figure to take 84 down to SLC and then down to Moab to spend some time there. We want to check out Monument Valley so might do that and then double back to Farmington and Chaco passing by 4 Corners on the way. There isn't much to do at 4 Corners but I've heard the Navajo sell Fry Bread there in a van and that it's pretty good. Our ultimate goal is to tour New Mexico....
