The roads are a LOT better than anything you drove on in a motorhome 15 years ago.........and if your last rig was a 5th wheeler, the total length was probably longer than what you're worrying about here.
Just relax, take your time, and enjoy the view. Remember, when you're in an RV, you're not supposed to be in a hurry.........you've got the wrong vehicle if you thought you'd be able to make time.
