Storing chassis for slow build

[D13]

Looking at a long slow build. Have the frame, going to do all new brakes etc. It will take me probably 5 years before final assembly. How do you guys store your chassis for long periods without the brakes rusting? I live in Michigan with temp and humidity swings. I don't have a heated building or a dehumidifier the size of a house.

I'm looking at stainless lines, possibly silicone fluid as truck will sit for a considerable portion of the time. Heavy 3/4 ton 4wd so rotors and hubs are $$$ and I'd rather not have to replace them bu once.
