Hi Jim,
Load support is, unfortunately, NOT voltage support. I have the Magnum 3012, and while it can be "forced" to do voltage support, I do not recommend that be done. Doing so may have caused damage over time to mine--and that resulted in the unit catching on fire.
What you need for voltage support is an autoformer.
If I were buying again I'd probably choose Victron.
The Xantrex can not be repaired--only replaced while still under warranty--so I would certainly not consider it.
I have my Magnum set up to do all house loads. I do have a Sola Basic autoformer. Hughes also makes an autoformer.

There are 4 I'm trying to decide on the magnum msh-3012 with a 60 amp transfer switch, the victron multi 12/3000 with a 50 amp transfer switch and the xantrex 3012 with a 80 amp transfer switch. The Quattro 120/5000 is really nice but it is twice the $$ but does have 100amp x2 transfer switch.
I understand you don't need to run the whole coach thru the inverter but it would be nice to have good clean power going to everything no matter what. Some of the rv parks I have visited in the summer have given me less than 100 volts which is really hard on electronics.
So my question is what do you run if you have a hybrid unit. Do you run the whole coach or isolate the big loads? I love the gadget side of this and it looks like the xantrex and victron have the most bells and whistles. The Quattro is nice because it has 2 ac inputs so I could hook up shore power and the generator to it for a completely transparent experience. But for $3400 for the unit plus $500 for the display it is pricey. So what would/did you pick for your coach?
