I know what is written. I have had an uninsulated hub for 6 yrs. I have not spent the night in it. It does build condensation over the day so I imagine a night of a heater, food and 3 people would add to the moisture significantly. My question is, is there really no condensation in an insulated hub and is one better than the other. I am less worried about the insulation as I am of the condensation.
