We don't have a Newport but we bought the Sequoia model new in 2004. It's the high-wall design that doesn't require flipping the galley prior to putting the top down. We took it last year on a 3-week trip from northeast Tennessee to Gardiner, Montana and had no problems. We love this model. We actually traded down from a 24' fiver to this pop-up and still have all the conveniences plus a lot more flexibility when selecting a CG.
Ours has a king bed on each end, 20-gallon under-floor freshwater storage, microwave, 3-burner stove/oven, double sink, 6-gallon water heater, and hard-wall shower/cassette toilet, all in a 14' box.
Hope this helps,
