There are two ways to control condensation, and by extension mildew.
First and most important, reduce the relative humidity. There are two ways to do this. You're already doing one of them by using Damp Rid. But you may not be using enough of it and/or you may not be replacing it often enough. A Damp Rid tub that's already full of water stops working.
The other way to reduce relative humidity is by heating the air. If the amount of water in the air remains the same, humidity goes down as heat goes up. An inside air temperature that is at least 5°F above the dew point (which can be determined by watching your local weather reports and forecasts) should be enough to prevent condensation on surfaces. But don't use propane to provide the heat— water vapor is a combustion byproduct of burning propane, so that makes the air
more humid. Use electric heat instead.
The other solution is to keep the air moving, because moving air will not deposit water vapor on surfaces. If you have a source of electricity, running your ceiling exhaust fans should do the trick, as long as you've got at least one window open to let in air to replace what the fans suck out.
How can you tell if you've got enough ventilation? If you can feel even a slight breeze on exposed skin, you've got enough ventilation. If you can't feel a breeze, the air is too still and it can deposit water on colder surfaces. Since the air flow inside a trailer isn't exactly ideal, portable fans in strategic locations can help bring air flow to dead spaces where the exhaust fans don't make a breeze.
Even in the balmy Gulf Coast areas like where I live, the right combination of heat, Damp Rid, and/or air circulation should keep your trailer fresh and clean.
Though if all else fails, I suppose you could bring in snails to eat the mildew…
