Dave,

It seems like you've got some seriously mutually exclusive wants/needs.

Not to worry, I think yhat I've found a hybrid that will meet your stringent
criteria:

"In most cases we matched or exceeded the Humvee's capabilities," said
General Dynamics' Tom Trzaska, citing improved mobility, recon ability, and
providing a better platform for employing a machine gun such as the M2 .50
Cal Browning. The RST-V also has a significant edge over the Humvee in fuel
economy. The average fuel usage for a deployed Humvee conducting an
extended reconnaissance mission is 1,040 pounds per month, but only 440
pounds for the RST-V.

"The RST-V reduces the foot print you have to take to the field through
increased fuel economy," said Trzaska.

It may also be used for light strike duties, as a battlefield ambulance, for air
defence, logistics, as a personnel carrier or as anti-armour and a mortar
weapons carrier once the System Design and Development (SDD) phase is
completed by ONR in 2005.

Propulsion System
The Shadow runs on a hybrid-electric drive based on a front mounted
turbocharged, inter-cooled common rail direct injection diesel engine, type
2.5 litre DI-4V rated at 114kW. The diesel engine powers a 110kW Magnet
Motors permanent magnet generator that drives four 50kW Magnet Motors
permanent magnetic hub motors, mounted one in each of the Shadow's four
wheel hubs.

The Shadow is fitted with a pneumatic suspension. It's dimensions can be
reduced by allowing the tyres to be pulled in (from 79in footprint to 62in) and
the height can be dropped so the base of the vehicle is 0.1m off the ground.
Crucially, this will enable transport by V-22 tiltrotor.

I suspect that you'll think that I'm joking...
I'm not, it is the only thing that I can find that would work for you.

I think there's an important question that still needs to be considered. Maybe
it's time for you to do some validation of your needs and desires. It just
might be that all you want just can't be got in a single vehicle. The question
then becomes;

What two vehicles might separately meet your daily commute
and heavy hauling needs?

And then maximize fuel economy for each.
