I would also agree - packing 5 pounds of whatever into a 3 pound sack as they say. You will be visiting most things at best; not SEEING them and enjoying them.
And not sure of your driving times here in the west with the mountains and traffic and tourist areas. With 4 of you and 2 dogs in the class C it can become "confining" as well and you will need some breaks! :-)
I am sure you have a reason to make such a large loop of places to see but you have a lot of long and tiring days in here with not a lot of relaxing time.
Just MHO.
