We are about a week from going full time and may have to get through winter in SW Michigan until I retire. My wife is sold on the Cyclone 4270. We are doing OK as far as pricing. A little more then I wanted and the Yeti Package is an additional 3000 dollars. The bell has insulation and heat, is it necessary to get the Yeti Package or can I just have heating pad put on the tanks...……………….thanks for having the forum and I would appreciate any input.
