We're looking at a 37' Tradewinds on a Spartan chassis powered by a 7.2L Cat 330 hp engine. Other than amenities and fancies, is it a reliable, long-lasting coach? I'd like to know more before I buy. I'm not worried about the engine or tranny, just the endurability of the coach itself over the long haul. I've not had any dealings with nor much knowledge about these coaches so if you know anything about them, share it with me........ I'd like to get one and keep it for many years, and drive many, many miles. I've got a good deal on one but wish I knew more about them. This is part of my homework..........Thanks for any input!
