I like your green decision, but am curious as to why diesel? (whats the benefit/or just something different?)
Just a few notes on side.
Diesel is cheaper, at least in majority of the world which America is not counted in (in Europe you pay 25% less for Diesel then Regular Gasoline, in US and Canada it sometimes 5-10% more expensive

).
Diesel engine is more economical (less consumption). You can get up to 50% fuel economy on it vs. similar Gasoline engine.
Diesel engines are pretty much simple and easy to maintenance compare to similar generation Gasoline engines.
Diesel engine is not that much affected to water, so it's better adopted for water crossings. Basically you can drive Diesel powered vehicle equipt with Snorkel with flooded engine bay and water level at your mirrors for hundreds of meters or yards.
Diesel engines usually have huge amount of torque available right at the beginning of power band and and have nearly constant level of this huge torque for majority of the band.
All this makes Diesel is as a superior engine for off-road, remote driving and towing.
Downside of Diesel engine is that it doesn't have a lot of power (new generations of modern Diesels now have HP close to Gasoline engines), so if you looking for a "Highway Rocket Car", it's not designed for it.
P.S. I'd love to have D-4D in my Cruiser, but it's way too expensive to convert, so I'm still running 2F.
