Hot Water Issue
Hey, Kids! There are a couple other posts nearby, that are close to my issue, but not close enough that I feel like hijacking their threads. My issue, which I have had for some time is just wierd. ...

OK so you have an Atwood XT Model (that info would have been helpful earlier)
The Mixing valve allows higher temp setting (160*F normal t-stat) for heating cycle (vs 140*F on standard models) and then mixing cold water for an outlet temp of 130*F (6 gallon tank becomes a 9 gallon -----10 gallon becomes a 16 gallon equivalent for hot water availability)
The HOT out from tank (mixing valve in) gets clogged with scale/crud due to hard water/lack of flushing tank and then only cold water flows thru mixing valve supplying hot water system
Removing mixing valve.....huge liability
Immediate scalding if end user does NOT mix cold at faucet
Water will continue to be heated normal cycle to 160*F which will flow thru hot water system
IF you remove the mixing valve for safety replace the normal t-stat with the standard temp one (140*F)
The t-stats are same size......go in same place ...use the same ECO (high temp t-stat set to shutdown at 180*F)
BUT you will need to remove/replace the terminal spade on Brown Wire
Normal t-stat uses a smaller female spade.....the mixing valve version uses a round pin terminal
Be safe.....scalds are life changing and VERY PAINFUL
XT Models are still available
