You did not define which is the black tank valve and which is the gray.
I don't see how to work the slide(maybe I missed a chapter)
Since you don’t have the BMPro, you need to see one to follow
What to expect from an absorption fridge.
Absorption fridges use propane to cool with and very little DC.
Where the wiper switch is.
Emergency jump button.
Both are on the dash
Where the water pump switch is.
The BMPro controls it. I hate that.
That the bathroom sink runs into the black tank so watch the usage carefully.
Tire pressures and where the gauge is
AFAIK, no gauge built in. 75 front and 65 rear
Windshield shade usage.
Switch on the dash
Not to open the emergency window.
The switch by the sink will make the front fan not work.(on a 2018)
Do not close stove cover onto a hot stove(the scuba rule)
How easy it is to twist a key off in a bin lock.
How to jump start if all goes dead(Mine has twice)
I keep a set of cables in the aft compartment, long enough to reach down underneath the passenger side lid to the battery and out the door to connect to another vrhicle
That's enough for now.
Let's see who else(and who doesn't) takes the time to read and respond.
