Narrower tires reduce pneumatic trail of your bike changing how it handles. The narrower tire is also potentially lighter which will reduce the gyroscopic forces that stabilize your steering. I like 35mm tires on my LHT. I've tried narrower, but went back to 35mm tires.
You should be inflating your tires for 15% of the measured width in vertical drop when sitting static on your bike with your planned cargo. The narrower tires will need more air to support your weight than the wider tires so you'll have to run them at higher pressures.
