For full time living, I think you are right to look at lights, airiness, windows. Our older model does seem fairly closed up when inside, and I love photos of the light and view in newer models. 4 season living needs that comfort level inside. I like all the models you are considering from research, but not ownership. All three companies are good, and those models are generally well liked. As far as the investment, do your research, and drive a hard bargain. It is near the end of the model year. I won't drone on about consumer buying techniques, but there are many. Ask if you want bargaining ideas from folks here. But briefly, don't be in a hurry to buy, don't show any weakness, the decision to pull the trigger is yours, and you control the final price if you want to. Good Luck. Let people here know what you do with your time though (work, what field; independently wealthy; other).
