Thanks, I have no choice but to drain the water, I used a big spike to punch out a few holes from the inside out. I hosed out the fins and cleaned it while in there, but it is not great cooling. Not even close to freezing meat in my 80 degree day. It is cooler and tolerable inside, but the top bunk is still hot. This is a trailer with a pop-up roof where the top 18 inches is what pops up, not to be confused with a pop-up. So, the canvas wall portion is not insulating at all. Maybe will replace it for next year as summer is drawing to an end now.
