I don't have that specific rig but on most I have seen the pump will be behind the utility panel. A partition in the storage compartment may have to be removed to access it. The back of the water heater will be there also but most access you will need is from the utility panel.
The converter will likely be mid way on a inside wall, look for the fuse/breaker panel access panel on the outside and the converter will be right behind it.
While familiarizing yourself with the rig, look around with a flashlight and a vacuum. You will likely find a lot of construction debris laying around that is easy to suck up. Don't ask why the factory don't find it as easy.
In my rig, I can see some of the tank sensors also behind the panel.
