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...

I think you are right from reading the manual where they use "chassis". It is true they all use the frame but separately, sort of.
See page 12 diagram. There is a "system" ground to the frame AND the neg from the battery to the inverter neg intake. Also there is an inverter chassis ground (equipment ground) to the frame.
Also something in there about the accessories like the monitor ending up as the neg path if you are not careful.

My Vector inverter manual has a special warning about the neg intake from battery and the inverter's chassis ground too.
Do not connect this (inverter's) chassis ground wire to the negative DC input terminal--it goes to a "solid electrical ground" ie the RV frame
