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...

I wouldn't know, specifically, but it does have the generator fuel pickup in the tank. I've been into the pillar behind the drivers seat as the switched chassis battery connection to the BCC (Battery Control Center) was incorrect - the chassis was not charging the house batteries when the engine was running. It has the heavy cable routed from the chassis battery to the BCC, but the control wire never sensed the engine run condition.
I learned of this location by chasing the wires, then researching, I found upfitter-bodybuilder documents online for GM chassis:
BODY BUILDER MANUALFOR 2015 CHEVROLET EXPRESS/GMC SAVANA ELECTRICAL SECTION.
This document contains a reference to the Auxiliary battery:
G305 - Left center outer frame rail,near the auxiliary battery
So I've learned something! Yea, that would be nice to have a third battery, tho as others have mentioned, it's a maintenance nightmare. We purchased the Sunseeker in October 2015 and have enjoyed several boondocking nights but we tend to travel between those events, thus charging the house batteries (after fixing the sense wire issue).
Based on this document, I have a 159 inch "14,001–16,000 lbs/Hydraulic/Commercial Van or RV Cutaway" chassis.
