RV Installation

[menalice]

The install manual indicates not to "bond" the "battery negative" to the "ground".  Well, this is a motorhome so all are the same, correct?  The only time it will have a true "ground" is when connected to the "grid" through the power cord.  Do I need to address this in any way?

No I think you are all set as an RV usually has battery negative and chassis ground as one in the same. You may want to verify that with a volt meter just to be certain.
