If you are going to be living full time. I would buy used high end model. You will get more RV for your money. Higher end tend to have metal frames, tank wash outs, and other niceties. I would stay-away from anything "lite". They were designed for weekend camping, and are lighter in framing. I think all Rv brands have their good points, and bad. Decide what floor layout, and features you want. Then shop, shop around for best price on the unit that best fits your needs. Ebay, and Craigslist have good off season prices.
