Besides AMP management the only real 24v upsides that I personally know for the G klasse is that you can take advantage of their NATO receptacles. Such as the one inside the engine bay. I've also seem some users use converters to acquire 12 and 24 volt receivables and bolt them onto the front of their G klasse to operate various tools from. Sort of like what the military spec Unimogs have. I think the Dutch do this to their own 290s. There's also a debate as to 24 volt rated heaterplugs to-be more effective than the 12s, but it's a rather biased topic. Negatives
All and all I've opted for 12 on my 250GD for the reasons Flanker525 mentioned. The costs. Acquiring 24 volt rated parts aren't worth the hassle, especially if you plan to have your truck for a good while. You're also expected to buy a second battery pack, adding to upfront costs. From my experience of owning a 12 volt 250GD I've had not a single issue with my heater plugs or electrical system. Not a one. Changing this 24 volt example into a 12 volt one is totally possible. And I'd personally recommend it.
