I am taking my trailer to Texas at end of July. 21' Terry Classic and my GM 2500HD. My wife and I are driving, and I am wanting to take 2 weeks to take her through Utah Nat Parks, etc. The Grand Circle assumes a round trip. Does anyone have advice on the order I should go and the sites to stop other than the Big 5? I would love advice on the minimal time to see enough of each place to know whether to come back on a return trip and stay longer. My plan so far is Canyonlands, Arches, then Bryce, Zion, Grand Canyon (North Rim), then maybe Carlsbad on the way to College Station.

I really don't know how long to stay at each site and with only 2 weeks or so, it is always a trade-off. And I am sure I am missing something!
Thanks in advance!
