I use my propane furnace for heat when boondocking. My furnace blower and control circuit board operate on 12v dc nominal.
My norcold fridge operates on propane when boondocking. It also requires 12v dc nominal for the control circuit board when operating on propane or 110v nominal.
The converter supplies 12v dc nominal from 110v ac nominal.
The inverter does the opposite.

Welcome to Mark's Fulltime RV Resource

The 12v side of life.
I am currently generator-less. The one I bought for a storm this past May was stolen off my porch two weeks ago. It would have fit in the compartment meant for it but it would have been a hassle to check level,refill fuel, etc due to there being only about an inch clearance.
What is the best choice for a more compact option. I was looking thru Harbor Freights catalog the other day but dummy me is confused as to how I would have things plugged into it with it in the bay. Is that where my pictured converter comes into play? Should I not buy the 4-6 marine batteries I saw for a good price today?

Sorry that some scumbag stole your genset. If it was me, i'd forget trying to use a cheapy genset and replace with a unit designed to fit in the existing generator space. The right genset would tie into your chassis' fuel system, tie into the existing wiring, and run the motorhome without too much worry of overloading.

The refrigerator will run on propane for a few days with good charged batteries. It itself doesn't draw that much wattage. Using lights or other 12 volt appliances brings down the batteries quicker so you would have monitor voltage more often to make sure it didn't drop below 12 volts.

If you have an inverter, you can run small appliances for short times. An inverter is not that efficient so battery voltage will come down pretty fast when it's used. Trying to run an air conditioner, electric heater, or microwave oven on an inverter probably won't work out well as the batteries won't last long.

The genset puts out 120 volts, the same that comes in through the shore power cord when plugged into an AC outlet. With either, the 120 AC volts goes to your converter/battery charger which then converts it to 12 volts DC. This supplies power to the 12 volt system and charging to the coach batteries. Good batteries are a must so take advantage of the good deal if you need them.

I don't want to use propane at all. 98% of our cooking has been reduced to microwave these days, showers (with hot water) can be free with fill up, probably going paper plate style to reduce dishwashing, etc.

Thanks for any help provided
In order for you to get the full usage from the features of your coach and to protect the transfer & inverter components (switches) I would say yes,

Do you have a "best" generator recommendation?
Another poster showed me these:

but 2000 watts doesn't sound like enough either.
It's not like all these items will all be running at the same time. Save for the fridge that is.
