[Vwdiesel] oversize alternator?

[Joe]

I have an off the wall kinda question... What would it take to turn my 82
Diesel Rabbit 2-door into a mobile backup power generator?  Something
capable of powering at least some of my home (important things like fridge,
fan power to oil furnace, etc.) yet still being able to be driven daily when
not needed as a power source?  Or would it be easier/simpler/cheaper to just
have a backup generator?
