I bid for my 3000 watt Pure Sine Inverter on eBay. It's just an inverter not a charger.
I won the bid on mine at $490 US. It's a Ramsond. Pretty happy with my purchase for the price.

All:

Just a point of clarification:

A square-wave inverter does not play well with motors or transformers.

A modified-square wave/quasi-square-wave/modified-sine wave inverter does not play well with sensitive electronics, florescent lighting, laser printers or stereo equipment.

The best inverter will be the pure sine-wave inverter. It best replicates utility-supplied grid power.

Before buying your new inverter, verify it says it is a pure sine wave inverter with less than 3% harmonic distortion. That is the tolerance level for some of the gadgets on our rigs. My changeover made a huge difference in everything run by a chip.

For anyone wanting a new Inveter/Charger, send me a PM with your e-mail address. I can check pricing. I would avoid Ebay as I don't think I want to get one which has possibly been reconditioned, or gotten out of a wrecked RV, without having it check by authorized service center. Magnum Inverter/charger units are field component repairable with new circuit boards. Xantrex used to be non-field repairable, don't know if the new line has overcome that limitation. FWIW - Xantrex RS2000/3000 work well with the coaches equipped with silverleaf, there is a software modification/reprograming needed for the Magnum inverters units. I don't know if this is something you can do yourself, or if it's something silverleaf needs to perform for you, and I believe that is going to cost money.

When I upgraded to the Magnum Inverter with my Silverleaf, I had no problem. I did call Silverleaf and they had no software update for a Magnum. All I did was not hook up their data cable and used the data cable for the Magnum to their remote and everything works great. In my opinion, by looking at my picture of the remote I posted, I have more information all the time on the remote screen. Magnum does have an auto gen start, that I chose not to put on. The thing I didn't like about WRV there is no remote start switch for the gen. inside the coach, only through the Silverleaf. Next to my Magnum remote, I installed an Onan combination start switch, hour meter, water temp, and oil pressure gauge. It was an easy install, just paralled into the wires on the gen. I can monitor my remote and start the gen when needed. I will post a picture later, when I find it.

Inverters come in 2x2 flavors, You have described the first 2 so I'll go with the 2nd, "Inverter/Converter" also called "In-line" or what I call Stand alone (Inverter only)..

SO long as your new True Sine Wave is of the same 2nd type as the original MSW the only possible problem I can see would be mechinical (Different size or shape of housing) .

Electrically you will have no problems at all,

Operationally: As others have said, You may find TV's Radios, and Audio gear work better on TSW, if you have the power to run other stuff (IE: Microwave) Same there.

Worst case: True sine wave is the same as shore power. No difference.
Normal case: Shore power is not that good. (TSW inverter is BETTER than shore power)

MSW: Well... You already know about it.
