Digger, find a good bike store and have them go over the spoke tensions.
Then in the meantime, start putting stuff together and putting it all into panniers.
ride, see how it is.
trying tokeep load weight to maybe 40lbs is reasonable, and of course you can go lighter. or heavier, but thats just more work.
in the meantime, yoiu'll see how your wheels handle this.
and as said, dont abuse the wheels when loaded, use common sense and dont crash into potholes etc.
