Water heater - how long should it run?
With my previous motorhome when using the water heater on gas it would take an average of 20 minutes for it to heat up and shut down. Now with my current motorhome it's more like 45 minutes or more be...

Atwood uses a disc t-stat for normal and high temp
Normal t-stat is pre-set for 140*F and the ECO (Energy Cut OFF-----HI Temp) is pre-set for 180*F
IF the ECO Opens due to failure of normal (not opening) then the 'fault light' (RED light on On/Off panel will light up and water heater will not operate again until you reset fault...by turning ON/OFF switch OFF then back ON.
Water temp also has to cool down to roughly 110*F before reheating cycle will occur.
Normal t-stat CAN allow longer run time IF it is NOT being held tight against tank wall. The t-stats are under the foam insulating cover and are held in place by: Plastic washer, spring and three small tabs that plastic washer has to be under. (Really a poor design)
Also connections of t-stats need to be tight and clean
Have you run that hot water into a glass/mug with thermometer in it and checked temps?
Heating time should be roughly 20-30 minutes (depending on supply water temp and amount of hot water used)
On Edit:
Just FYI----Atwood does have an adjustable normal t-stat, Replaces pre-set disc t-stats.
Adjustable from 110*F to 150*F Part #93105 (it's mounting bracket is flimsy)
