We leave Thur to go to three of the four places you mentioned. Again - many for 3rd - 6th or 7th time (Moab). And others including Capitol Reef and southwest CO...two months.
We are skipping Zion once again as all we get is a sore heck looking up - except for the beautiful drive in coming down from the east.
You say Arches - one of our favorites. There are many short walks / hikes in Arches.
There is the Island In The Sky (north section - forget driving way out to the south section) of Canyonlands NP out of Moab. Nice drive and short walks to observe this beauty.
If you can, I would recommend going over to Torrey for Capitol Reef NP. We love it.
In all due respect, I think busskipper gives information overload. And many, IMHO, not worth the time. And many far from where you say you are going.
If you do swing down to the Grand Canyon - and I suggest you do it if you can - you do NOT want to go to the North Rim; go to the South Rim. You only see 10% of the Canyon from the NR and have to hike to do that. The SR gives you lots of places to view from and includes many shorter walks.
Mesa Verde is OK and that is about it. It is great to see but it is a long drive in and then mostly ranger led longer walks. I would definitely opt to Capitol Reef instead.
I will PM you with my email address and my websites for you to view of these places.
Enjoy ........... be safe.
