To my knowledge, ALL RV chassis makers have the Allison ECU programmed to default to power mode each time the engine is started.
So, to get into economy mode, one must push the mode button each time the engine is started.
To verify you are in economy mode:
Next time it is safe to accelerate from a stop to 45 or so MPH, do so at WOT (wide open throttle) with mode button off (engine started, but mode button not pushed) and then again after pushing the mode button (red mode light on).
Yes, in economy mode, transmission upshifts at lower RPM and downshifts at lower RPM.
