Do you have any familiarity with the states? The National Parks are very majestic to be sure but it's mostly all pretty scenery. The vast expanses of the US are mind boggling to those of you from Europe. 2 weeks can be burned up in seeing just Yellowstone, The Grand Canyon and any of the parks in Utah. The big question you need to ask yourself is what kind of experience do you want to have. Do you want to drive long distances to see different landscapes or do you want to have some city type of entertainment at hand like visiting museums or brew pubs or wineries? What are your interests? The children are very young and will do what you do.
What type of RV are you thinking of renting? A large Class A motorhome or a larger Class C? There is no such thing a privacy in an RV really. They are just too small for much of that. Never having driven one before do you think you can handle driving it alright? Give us some more info on what you all enjoy doing.
