It was quite a shock to see how much moisture accumulated on the INSIDE of the windshield where, of course, there are no wipers to clear it - that was the biggest problem. I'll have to pack some microfibre towels for the next downpour, at least until I get a soft top and side curtains.

That is usually caused by excessive hot air in the driver's compartment. It sucks the cooler more dense air in.
