You have a 42-32-22 crank now.  You are looking at a 40-30-22 crank.  Other than reducing your high gear by a few gear inches, what would you gain with the change?  I'll assume you are using a 9 speed cassette with 11-32 or 11-34 now.  42x11 high is a fine high gear for a loaded touring bike.  Not too high, not too low.  You would actually use it some.  A 40x11 high gear may not be quite high enough for me.  But others might find it fine.  A 42x12 is probably equal to a 40x11 so you aren't really changing anything.  With 40-30 rings instead of 42-32 rings, you would use the smaller cogs a bit more.  But with a 9 speed cassette, you have enough cogs to use with any chainring size.  Again, what does this new crankset really get you?  Why are you doing it?

I am using 11-34t cassette 9 speed and I am also using Shimano XT M771 Traditional Dual Pull FD and Derailleur Capacity: 22 so 42-22=20 and 40-22=18 and I am staying with 22-32-42t

If you have 42-32-22 crank, and are staying with it.  Why did you ask about the 40-30-22 crank?

40 would be too small for me for road touring. YMMV.

I am just asking a ??? and I started with 26x38x48t in 2008 and gone to 24x34x46t and in 2013 I gone with 24x32x42t for Southern California rolling hills and the I added 22t and I seen the Shimano Alivio M4050 9-Speed 40/30/22 tooth on bikeman.com/ new for 2017 so that is why I am asking a ????!

Other than the slightly high 26 tooth inner ring on your first crankset, all of these choices are fine and dandy for loaded touring anywhere in the world.  I rode the Dolomites, Alps, Rockies with a 24 ring and 32 cog.  So it is a fine low gear for a loaded touring bike.  22 is a little nicer, but not earth shattering.  All the cranks you had or have are fine.  Leave your cranks alone and work on some other part of your bike.

I've been to southern California several times in my life.  Not as steep as San Francisco but there are hills.  A low gear is good to have.  Your housing situation is not too relevant to a discussion about bike touring.  100 pounds is far more weight than any normal person carries on a bike.  I'd suggest cutting that weight in half.

That is right answer to the question John and the Shimano Alivio M4050 9-Speed 40-30-22t crank set is about $68.00 at http://www.bikeman.com/ and there replacement chain rings in 96mm bcd in Shimano Alivio and yes in Shimano XT M782 11-speed $57.99
and it is cheaper to replace the Shimano Alivio M4050 9-Speed 40-30-22t crank set is about $68.00 and for now I am happy with Shimano deore 42-32-22 with Raceface chain rings on Deore crankset and when I seen the Shimano Alivio M4050 9-Speed 40-30-22t crank set and I said WOW 22-30-40t

That's a nice looking crankset ! I just bought this one from eBay a little cheaper( including bottom bracket) it's a 36 / 22  so my low gear is 22-36 !! It's pretty low but it is on a 29er which use a lower gearing anyway.  My high gear is 36- 11 which is okay I'm usually in no particular hurry.
