If you are mailing your belongings like we did, those heavy tools & flatware are great to place in the priority flat rate boxes....you can fit enough in that you have to monitor the weight to make sure you do not go over-limit (plus side, they pick up & deliver the priority boxes!)
We pared down sooo much (the books were hard to let go...but I realized that donating some of the very rare ones would allow many more to enjoy...plus side, at least 2 were electronically copied, & I still get to enjoy them...anywhere I am!
Dumb thing I decided NOT to bring - was my moms awesome hand juicer....go to citrus mecca without the juicer...DUHHH!!! luckily there is ebay....have found many (and have shared many with friends here) that were very inexpensive...
and there is always Amazon with free shipping... and going to rummage sales & such have even found exact replacements for some of my other favorite pieces... so not all is lost....
When shipping things, think of soft things like clothing & linens as potential packing (obviously not the good stuff, but even socks make good protectors!) also use those plastic containers...that way you will have them here to use....& when shipping your items, always remember that unless they are being shipped on a plane, they are going to be on a boat....movement will happen & cool, dark & damp can happen....
ADDED

ehumidifiers do work, but they also use electricity....sometimes looking at how to increase air flow & light (even our closet doors are vented with light through...and we replaced the solid closet ceiling with translucent panels to allow more light in.... )
Those Steven Kings can easily be boxed up with the proper care (desiccants & such)....also make sure the things you do box up are fairly clean...any gunk on the storage items will grow ucky things....
