Congratulations on your new coach Steve! We took delivery of our new Marathon (coach 1208) about 3 months ago and its been great (Alan Christensen really made the ordering/design process a productive and fun experience). We also have two younger kids (plus two teenagers but they take up too much space to bring them most of the time...lol). Anyway, let us know if we can provide any tips on traveling with the kids (Marathon just added an X-box which hopefully minimizes the "are we there yets"). Also, we are located up in Jersey and have a space with full hook ups if you're ever traveling through the jersey shore area and need a place to stay.
Good luck with it and let us know if we can help in any way.
Bob
