You didn't tell us what engine you have. For your sake I hope it's the 318 (5.2). The depth of knowledge from all sorts of gearheads for the 318 is enormous. The range of go-fast and go-long parts for the 318 is stunning. The flexibility of aftermarket modifications is fabulous.

NOTE: Mr. Sharkey's pusher trailer was, in fact, a diesel VW Rabbit nose that would push his EV on long trips. In retrospect if you wanted to make your van into an EV and have a diesel for cruising, that's a concept worth exploring too. In any case you could aerodynamically couple the trailer to the van, and it would contribute a net gain on your fuel economy even when it wasn't pushing, in addition to allowing you to move some storage out of the main vehicle.

How does a gas-electric drive system push at the wrong potentials? The generator I am looking at is harborfreight com>engines-generators>gas-engine-generators>13500-peak11000-running-watts-22-hp-670cc-gas-generator-epa-iii-61725.html . Yes I know it's a cheapie and won't put out clean power. Also, What price range is a low-end motor controller and traction motor to propel the van? Perhaps pick the motor(s) and controller out from a wrecked EV to lower cost?
The engine is a 5.2L 318 V8, very lucky to choose a van a common and cheap parts.

A pusher trailer was something I thought of as well, with an ultra-efficient engine on it to push the van 100%.

A best-case scenario would probably be to find a small diesel that you can bolt onto your existing transmission, and if you're feeling particularly adventurous, an auto -> manual conversion with taller gearing.
A new ultra-efficient drivetrain would cost more to upkeep than the fuel savings. This is why I can't afford a new car; the registration, insurance and maintence on newer cars cost waay more than on older cars.

Diesel has a more stable price than gas, meaning diesel see sales much less often than gas does. Once could stock up on gasoline when it's on sale and have lower running costs than diesel.

I noticed nobody answered any of the questions from my feasibility and cost effectiveness checklist. I need somebody to do the math to see if this gas-electric system has at least double to quadruple the eMPG?
