This product, like DriZAir, likely contains calcium chloride (the same stuf Yukon Terr puts on the gravel roads to keep dust down -- The CC pulls in moisture, which then dampens the dust slightly).
Really good for storage in humid areas -- What I would do is make a drain and place the unit in the sink so the extracted water flows right out of the egg. Either that or suspend unit over 5 gallon bucket. I'd also have a small electric fan to circulate the air.
When egg (or any RV) is in use, some cross-ventilation is the key. On my 91S13, I have a small sliding window in the door and a small crankout above the range. I also mounted my fantastical fan in roof roughly on same line over the two.
Whenever I am heating with vent-free heater, I keep door and range windows
slightly open for fresh air, plus I open ff or the rear vent a tiny amount to let the hottest air (which holds the most moisture).
When I am cooking, I open crank range window and set ff to slow exhaust -- This pulls the cooking by-products right up and vents them outside.
Condensation is going to be a fact of life in any RV, or anchored home also, and it just needs to be understood and dealt with.
