Is it a battery and what I think is for?
Howdy all, In preparing our motorhome for an impending trip, I went under the chassis on a creeper looking for potential troubles yesterday. That was when I noticed, for the first time, what appear...

My 2018 Coachmen Freelander 21qb has the same frame-mounted battery (on a 2017 chevy 4500 express chassis). I spent a bunch of time in '18 trying to find out what it was. Like you, since it was near the generator, I thought it was a starting battery for said generator. However:
It is called the "Isolated 2nd battery" option. Isolated 2nd Battery — allows 2nd battery to be used when the vehicle is not running without affecting ability to start the vehicle ....
That’s it, Man!
I feel like I was drilling and drilling, and hit the oil reserve!! How did I make it prior to the time of World-Wide-Web and on-line forums is beyond me…
Kudos to @Newbiecampers for providing this much sought after information.
Now it all makes sense; Chassis manufacturers usually don’t like RV makers to mess around with their chassis lest it voids their warranties, so this hidden battery has got to be part of the vehicle features/functions.
This explains the other peculiar Chevy truck/chassis behaviors I observed and was puzzled by. For example, the two DC power ports (i.e. cigarette lighter) on the dashboard are always present whether the key being in or not. The first time I realized it was when I reviewed the dash cam recordings caught me to and from the restroom at a gas station. The 115VAC socket next to them, however, is on the engine switch, prompting me to think that the inverter is hooked up to the engine battery.
Well, mystery solved and my curious mind can rest. Thank you all.
