If you are completely set on this trip, I would suggest you have a backup plan ready in case the motorhome becomes undrivable for any reason. I'm still working on getting one I bought in July ready for a shakedown trip to a state park 10 miles away! Also, moving "stuff" as well as your travel needs in the MH may put you over the recommended weight. I read a suggestion elsewhere to take the loaded MH to a truck weighing location and weight each wheel independently to see if any corner is overloaded. Even if she is not taking furniture, clothes and kitchen items can add up. And have a great trip!
