Ihave a 2006 Tropi-cal. 39 feet deisel pusher. For the gentleman that was asking about National RVs all I have to say is that I love mine. I recently took a two and a half month trip from Florida to Las Vegas to the Dakotas and back through Michigan to Florida. At 13,000ft we had no problem going over around and through the Rockies. The coach drove and rode well. I had spent many days driving 12 to 14 hours and felt quite comfortable at the end of the day. I have an engineering backround, so before I invested a large sum of money into a new RV, I looked to see how the coach was built. I am very convinced that they built one of the sturdiest coaches in the industry. I am also very saddened by their chapter 11 filing. If I had the money, I would by the company myself.
