Orion xs install help

Hi all, I’m planning my install of an Orion DC into my RV. My concern is relating to the Negative coming from my RAM 1500.

Please see my schematic for my intended installation.

I understand, Victron state the Negative should be directly to the battery NEG.

RAM state grounding to the vehicle chassis is recommended.

My thoughts are that the Negative coming from the RAM only need to run 3ft from the chassis to the connector (125a Anderson), saving 20ft of 2AWG cable.

In the RV, Negative and Ground are connected via the Victron Distributor.

Has anyone got recommendations and/or have done a similar install?

RAM Cable run - 24ft
RV Cable run - 23ft

thanks!!!
