Thank-you for the suggestions and advice. I think we are going to go to Missoula and take US-93 south. We want to go to the St. Anthony sand dunes as we have a small car and a Polaris RZR(to ride the dunes) in the trailer. US-93 would put us closer to the sand dunes.
After that, we will head down I-15 and then take US-89 south to Bryce Canyon. After Bryce, we will keep going south on I-15 to Vegas. We are hoping that the weather stays the same as it is for another week or two.
Thanks everyone for letting me know that either route will be no problem for my combined length. I will watch the weather closely.
Thanks again...Don
