DampRid drop-in much better than the granular option
We found changing our Damprid jars to the new DampRid drop in tablets much better option for our use. We make sure the holding container is empty before travel and avoid the mess of a jar being tipped over during travel.
We keep these in the storage / tool compartment and in the bathroom and living area. We used to use a plug in dehumidifier but found these actually work quite well even with the rig parked for winter.
