The most efficient body type RE: fuel?
 
This might just be a thought exercise (hopefully a fun one), and not really applicable in game, but on my walk this morning I started to wonder what the most effective vehicle would be for a Chassis&Crossbow (or any resource gathering-type) scenario where one needed to burn/carry a combustable fuel source in search for more combustable fuel sources. In CW vehicle terms, or in real life.

Say, in one vehicle type I burn 10 gallons of gas to find 12 gallons of gas. In another vehicle I may burn only 3 gallons to find that same 12 gallons, but that vehicle would probably be smaller and lighter, and would have a smaller maximum capacity, and therefore potentially less range. However, a larger vehicle could carry more fuel, but would be heavier, so potentially less efficient at burning the same fuel. Are smaller engine (generally) more efficient than larger engines?

So I guess my question is, what would be the most efficient weight to space to fuel efficiency ratio to apply towards creating that next C&C vehicle, or just owning something in real life in preparation for the big day? :) All fuel sources are equally efficient in this scenario.

Apologies if this is too abstract or weird, but I'm a terrible numbers cruncher. And I can't help but think of a quote from I THINK Patton Oswalt, where he talks about a movie critic in his home town reviewing the Road Warrior to something akin to, "I don't get it! It's a bunch of guys with no gas driving around in the desert looking for more gas!"

I am not sure that question can be answered as it stands.

The obvious answer would be a fuel tanker. They exist in real life and fuel companies will have done the maths.

You also need to consider the available resource. A vehicle that burns a gallon of gas every 10 miles but can carry 5000 gallons is more efficient than one that only burns a gallon of gas every 50 miles but that can only carry 100 gallons.

But if you only find one gallon of gas every 10 miles you do, you are never going to fill that big tanker.

smaller engines are more efficient, so the answer in some sense is a subcompact. A better answer might be "The smallest car that will carry the fuel you will consistently find."

A Trike would be best . Both Light & Medium can use an efficient 1 Space Gas Engine & have more spaces available than a Sub .

Also without OR Suspension , they suffer minimum penalties for going Off Road - especially useful as Roads are in so poor state after the collapse .

If you compare power factors (i.e. hauling capacity) vs mpg the larger gas engines are more efficient.

For real fuel economy however you need an oversized vehicle. The largest gas engine is capable of hauling 90,000lb for 5 miles on a gallon of gas. With a even a well armed and armoured rig 40,000lb of that could be payload.

You would need 100 of the smallest gas engines to haul that (and far less would be payload). They would also burn 6.25 gallons of gas for every mile between them.

This is true if you're regularly going to encounter stockpiles of 6000 gallons of gas. If you're not, you're burning a lot of gas to haul empty space.

True. Available resources would determine final vehicle size. Like the vehicle is "adapting" to its environment. Which, of course, is obvious when said aloud. :)

Again, I'm not trying to shatter any minds here. Just thought it was something that would be very specific in certain scenarios, leading to potential success or failure for the character or group (or me and my gang in the post-apocalyptic future).

And since I just last week hit the road for 10 months and tossed most of my stuff away, I've tried to par down to a bare minimum amount of stuff to get around: two medium backpacks. Or in a dramatic CW term, a bare minimum to "survive." As with the above fuel concerns, what would be the minimum amount of STUFF needed to survive? If in a tanker truck or on a motorcycle, this could vary, because the more space you have the more crap you have, but there would still be a minimum: water, food, band-aides, weapon(s), etc.

And again, the minimum is going to be heavily dependent on how hard resources are going to be to find. When I backpacked in the Great Lakes, I took two 1-L water bottles and a filter, because who wants to schlep all that water around when the lake is right there? When I was in the desert, I took 2 gallons out with me every day, and it was more than half of what I was carrying.

With the attrition rate of CW vehicles, anything you cannot carry on foot is vulnerable. 6 grenade equivalents (or 40 lb if you use the alt. encumbrance system) is about all you can manage to carry if your ride is totaled. You probably won't store that much else in your vehicle either (maybe some vehicle specific items - PFE, toolkit etc) for the same reason.

I can see people living from truck stop to truck stop.

Back when I used to do a campaign, we carried salvage around in dirt-cheap lightly armored trailers towed on explosive hitches. It was easy come-easy go, and if it became a liability, it was jettisonned.
