I would be interested in a hybrid truck, or maybe a diesel. Diesel now though is no price break over gas (little if any). For some reason (big oil?) these options are not being offered in the US. Yet at least. My latest plan is to keep the truck purely as a once a month hauler, since I'll likely get very little trade in on a 16 year old Toyota. I'd then buy a hybrid people car (likely an Accord) and take over my wife's Pilot. Later, when a decent truck option comes up, I shuffle the deck again. I don't really want to end up with 4 cars (I have a young driver needing a car in the fall). FWIW - Spoke with a Toyota mechanic a while back who had just serviced a Land Cruiser purchased in England (or Spain) with a TDI engine. The owner is on a round the world drive apparently. He claimed that driving across Canada he was often getting 60 MPG. Seems like a lot of mass per gallon but I hope it's true.
