I know of a few folks that have done it and are really happy with it. There is a lot of information on installs out on the web. Inverter and battery wise it would depend on what you already have on board.
I personally wouldn't consider it simply because I'm a dry camper and need to be able to run on propane as well, but if your trips between shore power are short, you might really enjoy it. Repair costs are so much lower, more temperature control, overall more storage space, not having to be so concerned about how level you are, and the lower overall maintenance are pretty attractive.
I do know that the install can be a bit tricky with the spacing and such. I would do some serious research. I would love to read a follow-up if you decide to go ahead with it.
