Inverter Reccomendation

Just picked up a 94 Gulfstream, we are looking to have everything run while we are on the road, as were going from NY to Florida. There is no inverter or generator. Everything is pretty much 12v or propane and runs while we're going, except for the microwave and roof top AC unit, which I assume are 110, as per previous owner. I'd prefer an inverter over a generator, can anyone give me pros, cons, and recommend an inverter that would do this for us ? Thanks in advance !

What do you want to run off an inverter? Everything, including the rooftop A/C and the microwave? You'll need a large battery bank, probably lithium iron phosphate, and at least enough inverter to cover the peak demand.
Then there's the issue of recharging/replenishing the energy you've drawn from the battery bank.
I'm thinking adding an inverter/generator would be an easier and less expensive project. Is the motorhome set up to have one permanently mounted underneath the coach somewhere? Like an Onan Microlite or other?
Might as well add some solar up top, if there's enough real estate left over?

An inverter will not meet your needs to run the Air Conditioning continuously while you are traveling. You would need at least a 3000 watt inverter, maybe a 4000 watt to cover starting surges. A 15K BTU A/C draws 17 AC amps at steady state - that equal 170 DC amps. Have you got an alternator to handle that load plus other normal alternator loads? Then there's the DC cables to the inverter, probably need 0 gauge cables.

I would install a generator to run the 120 volt. It would take a large inverter and battery bank to run an AC unit.

Check to see if you don't already have a converter that acts as a batter charger when plugged in.

Almost everybody who runs AC underway uses a generator.

Only a few, well designed, expensive systems, run AC for any time while driving.

So, like I said in post #2, probably not going to happen.
Option 1 - run the dash air in the motorhome, and use the propane cooktop to cook with.
Option 2 - install an inverter/generator, like an Onan QG 2.8Kw Microlite and plug the A/C and M/W into it. Or, if you're a diesel chassis, maybe a QD3200 model. Your rig is probably set up for one. Did the seller say what happened to it?
Option 3 - Install 2000Ah worth of LiFePO4 batteries, connected to a 4,000W PSW inverter, and add a lot of solar panels up top to (help) recharge the batteries during and after use. NOT an inexpensive option.

That generator is not an inverter generator. Its a constant speed 3600 RPM model.

Still a OK generator for a Class C MH.

Of course. Bad example.
I was thinking on a budget, you might be able to mount a remote start portable inverter/generator where an Onan may have been mounted at some point in the past, and run an extension cord inside to run either the A/C or M/W. Or both. Awkward but possible.
Or, budget permitting, install an Onan where the missing generator might have been if it would fit. I was thinking there probably was some sort of generator to provide an alternative AC power source besides shore, on that rig at some point, and it's been removed.
My typing fingers weren't paying attention, as I was thinking. Happens a lot as I wander through senility.

Your thinking just like me, after on here everyone told me no to the inverter, I started doing some research and yes it would be nice to get a new Onan, but prices are crazy. It has the vented compartment for a generator, but its gone, so I'm looking at a Champion 3100 watt inverter generator with a remote start/stop key fob. I think it would work great would have to fab up some mounts and run the exhaust out the bottom, wonder if anyone has ever done this ?

I've seen them set up on trailer hitch basket mounts, rooftops, and I believe some have replaced their (missing) originals with all sorts of portable inverter/generators in the OEM generator compartment.
Figuring out the exhaust thing would be a serious safety issue, but maybe some sort of Genturi-like system could be plumbed into it. Get one with a remote start, and a big fuel tank, and run a heavy gauge extension cord(s) up into the motorhome, and you might be in business.

With a bit of searching on craigslist, ebay, facebook market, etc. It is often possible to buy a used take out RV generator for around $500 -$750, sometimes less. These are often fairly low hour units that have came out of motorhomes that have been scrapped.

I'm not too worried about the exhaust, I'm a pretty good welder and been building cars and motorcycles all my life, I'm sure I could fab something up, the existing hole is there and there is a junction box, I could just tie in a plug direct, the door on the box is heavily vented, just wondering if there would be enough cooling. Even with a factory unit, I wouldn't be comfortable sleeping with one running anyway.And yes that unit is remote start.

Yes I've been looking, but they are very old units with exposed exhaust I'm not crazy about or the nice newer sealed units are very crazy money, even used !
