The bronze bodied LN tools will not corrode but their blades might. So wrap the blades in an oiled cloth.
Put a heavy coat of wax on everything else.
How many of us have obtained cast iron tooling from damp basements that, with a little elbow grease, shine right up and work as well as the day they were made? I should expect your bandsaw, DP, t-saw etc to do well if oiled and waxed and put on casters so that they'll move easily.
Sticker and crate the lumber yourself. You're the only one in the room that knows how to treat it right.
I see no reason why a plywood chest with the remainder of your hand power tools wouldn't survive a couple of years of storage in a dry, constant temperature and humidity facility.
That last point is probably key. You gotta know where this stuff is going and how the place is operated. The run of the mill mini storage shed on the side of the highway probably isn't what you want. Finding the right place may be more trouble and expense than you've bargained for.
(If the storage facility makes you worry about your tools, what might your matresses, sofas and clothing smell like when you get back?)
You sure you don't want to lend us some of those tools while you're gone?
