Well its easy to get to when the slide is in:
(Note the above is from a dealer's website so I'm guessing it may disappear if the unit is sold).
In the image above the small hatch in the middle of the slide below the slide is the access to the dump valves.
The hatch in front of that is the propane tank (and the one in front of that under the drivers window is storage + the front fuse panel).
If we go down the side front to back the hatches are:
- Storage + Fuse
- Propane Tank
- Dump valve access panel
- Black tank--yup that big long one is not storage its where the black tank is
- Storage (top rear)
- Generator (bottom rear)
On ours we don't put the slide out until I have the sewer connected, and similarly when leaving we'll put the slide in first so I can get the sewer disconnected.
