Atwood Aluminum Tank should not be going thru much contraction/expansion when using hot water
(140*F in use...drops to 110*F then reheat cycle occurs)
Could be the check valve in Hot outlet nipple making noise when using Hot water
They are cheap plastic junk ....plasitc plunger/spring/O-ring assembly Scale/calcium build up---valve can chatter when water flows thru it
And then they fail------diminshed flow/no flow
