Make sure you get Passport America, we use it extensively. We stayed at Root 66 next to the petrified forest, It got bad ratings, but we enjoyed it. Went to Cadillac Ranch, kind of neat. Stay away from Tucamari, It was a dump, don't stay at the motel there, one of the worst places we stayed. We camped at the campgrounds near Arches, Canyonland, and Zion. Great campgrounds, They were National campgrounds. Great trip and enjoy.
BTW, you can sign up for Passport America on line and print out their card. You can download the app to your phone. Some of the campgrounds are really bad, but go to parkreviews before going to them. Also read the details for PA and make sure you meet the requirements for the discount. Some Sunday thru Thursday only etc.
We are driving a Dodge Durango and pulling a Evergreen G269FK. We also have two Cairn Terriers. 2 Champion Generators. This year, planning on 6 months in our Evergreen visiting, California, Michigan, and Ohio. We live in Florida. Grandkids, and dogs are why we camp. Also have a Hensley Hitch which that eliminates all sway. Pricey, but worth it.
