I have toured Beaver, Monaco, Country Coach, Spartan, American Coach, Newmar and Entegra factories. In every case the tour was revealing and informative. You will find there are more similarities than differences in technique, although some things do stand out. Some seem more highly organized, others chaotic. Some techniques looks superior but they all seem to work pretty well. Why not take as many tours as you can and see for yourself?
