First off, I believe you have confused yourself somewhat with terminology. You have a Converter, not an Inverter.
Sorry - had happy fingers - I meant to type converter, but they typed inverter
If I'm not mistaken, some older Converters will not provide 12 volt unless there is a functioning battery connected. I believe your battery is dead.
will check that
Most folks here on the Forum will recommend replacing the Converter with a Progressive Dynamics with Wizard, even if your current Converter is OK.
will look at that also

I would pull the inverter. Run it on the test bench. If you can get a schematic you may be able to find out what is wrong and repair it. Providing you have some equipment. To hire someone to repair it probably would cost as much as a new one.
I pulled it out of the circuit by disconnecting wires coming out of the converter from the battery and fuse panel. Then I could get 4 volts. I could trouble shoot it myself, but the time and $$ to get a schematic and chase down the parts would exceed the value of replacing it.
If initially a battery was bad in the RV like freezing, shorted plates etc. it could very well pull too much load on the inverter and destroy the output transistor.
Dont think freezing is an issue. Everything was working a few days ago and it hasnt gotten below 70F around here.

X2 on the battery. The Parallax 7155 I think requires a good battery presence to operate an RELAY inside the converter before it will work. Some of the older converters require the battery to be in the circuit to enhance their internal poor designed regulation circuits.
will do
This would be a good time to replace the battery with two 6VDC gulf cart battery wired in series and that will give you a big 220AHs of capacity which is what you need if you ever are going to do any OFF THE POWER grid camping.
The golf cart batteries were already on the list, (along with a bit of solar) just wasnt planned for right yet. Trying to keep control of the budget
would also start thinking about replacing the 7155 Converter with a Progressive Dynamics PD-9260C Converter
researching that as a replacement.

That Parallax converter may have internal fuses on a circuit board. If it's now non-functioning and there isn't a warranty involved, you have nothing to lose by opening it up to check for blown fuses. Check for incoming AC power initially, as mentioned.
There is an onboard fuse and it is good. Besides if it was a fuse issue, I would not get 4v when all load is removed
I would check the battery connections for correct polarity, too. Who knows what has been done previously.
everything was working a few days ago and I re-verified that everything is connected to the correct location.
I am checking out the suggested CONverters (there - I typed it correctly in spite of my beer soaked fingers! ;))
