Uneven joists at rim joist on my deck

I was wondering how others have dealt with the situation of having uneven joists at the rim joist of a deck.

The problem is due to the differences in the sizes of dimentional lumber. The 2x10s I used range from 9 1/4" to 9 5/8, which gives a 3/8" difference between the height of some boards at the outer edge (rim joist). They are all even at the ledger.

My thought was to use a hand planer to plane down the biggest ones, and use small shims to lift up the small ones until they are all even.

Does this sound like a good plan?

The variation in the thickness of the boards is only temporary due to the moisture content in the treated lumber.

If you plane anything from the joists now, you will just create permanent variations in the thickness of the lumber when it dries.

The simplest method is to fasten the lumber along with the joists so that the tops of the joists are even along the top of the rim joist/ledger board.
