Seems like we will need to use more freeways than I had hoped in order to access RV parks on our trip. This is what we have planned so far:
Day 1: from the U.S. border at Blaine, take I-5, 2, 203 and I-90 to Yakima, WA
Day 2: 82/84 to Caldwell, ID
Day 3: 84 to Ogden, UT
Day 4: 84/80, 189,89,6, and 191 to Moab, UT. We are thinking this route might be easier than taking the 15 straight through SLC. Does that seem reasonable?

Thanks again for any input that is offered.

Utah has spent a lot of money on I-15 thru the SLC area. It is now 6 lanes in places, and the traffic at afternoon rush hour was traveling 70 MPH in the left two lanes, 60-65 in all other lanes.
Left two lanes are truck thru traffic. I run the second lane from the right, at 65 because the highway improvements start at Ogden south.

Getting thru SLC area is not a problem any more.

Using 80/189 to Provo doesn't get you out of traffic, as much as I-15 to Spanish Fork and 6/89 to Moab.
We've done it both ways, and found it easier / quicker on I-15 and a whole lot less nerve racking.
