Inverter grounding to batt or chassis
I'm looking for some input regarding the ground (negative, not neutral) connection for my 1800 watt inverter. I need about 10 of wire to run it back to the battery or I can ground it to the motor hom...

OP here. I'll have half my battery bank on the curb side of the motorhome and the other half on the street side. To wire the batteries in a balanced fashion will take extra wire length. This is most of my motivation to ground the inverter DC return directly to the frame. I'll use a tin plated lug which is galvanically compatible with the steel frame. I can also use a chrome plated bolt so that the bolt will be galvanically compatible with the steel and tin.
I have a diagram a member from back then posted in 2011, but the dropbox has expired. He had a similar situation with two battery banks separated like that in his MH. (two sets of 6v pairs and a 2000w inverter/charger with an 80 amp charger)
For the neg side from each set he ran a wire to frame ground. On the positive sides wires to a 1,2, both switch, from that switch to the inverter pos intake. Inverter neg intake from frame ground.
