Welcome to the group
...You will get lotsa advise...IMO...All the important and expensive things, fridge, AC, stove, microwave, generator, engine, chassis are all common in a variety of coach builders. If you get an extended warranty all or most of these will be covered. National made very nice coaches, so I think if you are happy with the floorplan and the deal..Go for it. You will love the fun
.Again. Welcome and Safe Travels
Peace...D
