My wife and I are smitten with the Sundance 3400, but we are wary of the buying/negotiating experience. The dealer we visited was insistent about selling the one on the lot before taking an order for what we wanted. To be honest, we probably don't really know what we want although we have some ideas about what we don't want. Will somebody help us figure out how to go about this? Between interior decor and electrical options, we are a bit lost and don't feel like the dealer has our interest in mind. Thanks!
