You would appear to the THE expert on this.
How would the dessicant type dehumidifiers compare to a "real" dehumdifier as far as moisture goes for winter storage? Obviously a TT isn't being used in storage and moisture being created. Ignoring the issue of freezing, would a dehumidifier do a better job? Or are dessicant types better because you use several (one in each room or area)? We used 2 last winter and were surprised to see how full the containers got and was a good thing I checked before they overflowed.
On a somewhat different but related note, how would a person figure out what size or how many dehumidifiers to use in garage workshop at home? Had a hard time finding good info. by googling. Have about 1000 sq. ft. shop that I have lots of valuable tools and vintage car parts in that I don't want to end up with damage from humidity (rust & mildew). Maybe just one or two ordinary 70 pints ones? I guess I'd have to pipe them directly into a drain.
Not sure I'd qualify as an expert, but do have some experience and things I've learned I will pass along. For background, we live in western oregon, so we get lots of winter rain, and often pretty high RH in the winter.
Question 1: I've used the "dry the air" canisters for years during storage. I also store my trailers with the upper vent cracked open. This seems to work reasonably well, good since our storage area doesn't have power. As you've noticed, you just need to check them and refill and empty as needed. I've also noticed that a trailer with a proper cover, (not blue plastic, but a real cover that breathes) seems to help interior humidity and keep the trailer much cooler in the summer, warmer inside in the winter.
you could run a real dehumdifier, but IMHO only if other stuff doesn't work. you'd need a way for it to drain outside, or be emptying it pretty often.
Question 2: I'm sure a lot will depend on your typical RH. personally, I'd try one of the medium sized ones (70 pints maybe) and see how it works. Give it a few days to pull humidity down then see how it does.
hope this helps.
