Ok What Am I doing Wrong!!
We bought a new to us fifth wheel, traded in the old one so I am in the process of moving everything that I had in the other one to this one . I built a battery box for my 2 6volts , hooked up the pos...

This one
but I paid $240 for it as a store clearance. Also I see that there is a small grounding post under the main terminals on the right hand side, should that be grounded to the rv chassis? (installation instructions are pretty much worthless and don't mention anything about the grounding post)
I have that inverter. It does a good job. It does spark, don't worry about it.
It has two sets of terminals. you use two sets of #4 no more than 3 ft long. (sometimes sold by CanTire with that inverter as part of the deal) One set of #4 is not enough. Even so, I like to use the fatter blue #1 cable CanTire sells for my inverter/battery instead of those #4s
If you use one set of fatter wire on one set of terminals, that is still wrong, because inside the inverter it is in two halves sort of, so if your load is over about 1000w then that one "side" will be overloaded even though the wires are fat.
Use a length of #8 to go from the chassis ground to the frame directly. DO NOT bring that wire around to the neg input terminal of the inverter as a way to eventually reach the frame using that path. Go direct to frame independent of other negs.
You need a least four batteries to run big loads like a microwave.
You can plug the RV cord via 30/15 adapter into one of the three 15a receptacles and turn off the converter (to not have a "loop") Put the fridge and water heater on gas. Unplug the television when not watching it since the tv is always on when plugged in and drawing from the battery via inverter. You are now doing "whole house" same as if plugged into a 15a pedestal, but you must use "power management" not to pop the inverter's breaker for that one receptacle.
You can get more power up to the 3000 by plugging something into another of the three receptacles.
I always turn the inverter off with that remote when not running any 120v loads. It is hard to see that dim green light in the remote that shows inverter is on. I stick my three-light tester (which has brighter light) into a receptacle to show that the inverter is on. You could use one of those night -light things instead.
