Best Three Season Bottom Floor Insulation
Been trying to wrap my mind about how to go about insulating the bottom of our three season trailer. Our little Sunnybrook Harmony has exposed tanks and I am in the process of installing tank heaters....

One thing to keep in mind is that when you do that great job of insulating your underbelly area, if it gets cold enough that your tanks freeze, it will take a long time for them to thaw out. If you have some additional heat to prevent them from freezing, and thaw them if frozen, and that's the best way to do the job.
I had a friend who did an absolutely great job insulating the underbelly of his TT with spray foam, and then covered the underbelly with alum sheeting. Friend and GF were going to ski in AZ for a few days, then move on to Colorado for another week. They skied a few days in AZ and they didn't have time to dump their tanks before driving to Colorado. No problem, he thought, I'll just dump when I get to Colorado. Then drove 2 days thru extremely cold weather to arrive at the Colorado ski resort. When they got there, they discovered that their gray and black tanks were FROZEN SOLID, could NOT dump, and it took a LONG TIME to thaw out. OOPS!!! Great insulation job.
