Mine is in the front storage compartment with the landing gear.
I just went and checked again there.
If it is there, they hid it well. LOL
My trailer has the covered underbelly and I am afraid it is under there, but don't want to drop that unless absolutely necessary. Hoping it is somewhere else.

A lot of them are behind a partition wall in the front passthru area. If the slides are still working you can have someone operate them while you go around and listen for the motor running, to help narrow it down. Of course that won't help if the pump won't run.
