Hi, lots of questions and hopefully some answers from all of you helpful people. My wife and I looked at a local 21 and are hoping to order a 2017 when they become available. We are looking to get the thermal window package and extra insulation along with the heating pads and spray foam underbelly. Is it worth getting? We plan on pulling out the trailer in January and heading south with it. Anyone have problems with the extra insulation in terms of condensation? Also the outside shower, any problems there? I know that as I think about it I'll have plenty more follow up questions. I am grateful for any answers and thoughts that you might have. Steve M
