In the 80's Volkswagen had a great thing going for a beginner or light hauler truck with the Rabbit diesel. MPG was around 45. Certainly ahead of their time and too bad it didn't continue on. They do have a small following now. Also Dodge and Plymouth made a car truck in the 80's that was a little sporty.
Bought a 2007 Avalanche demo in 2008 and it's been one of the best investments I've made. Never used it as an everyday vehicle but was ideal for all the family road trips, roomy and comfortable, greasy acquisitions along the way were comfortable in the back and tools were safe from prying eyes. The roomy side boxes are great for additional out of the way storage and work well as a cooler, just add ice. Comfortably tows an equipment trailer with a car or tractor, did a lot of towing with it and I think the average fuel economy is still at 17.3. I never noticed any excessive noise or rattles. Solid performer and only repairs other than usual maintenance were the airbags and the clunk in the steering that was just annoying. I remember test driving the Avalanche and 1500/2500 pickups and there was no comparison in ride and practicality. I've been ridiculed by truck owners but the joke's on them. I think it was short sighted for GM to cancel it.
Cool little trucklet! Is that your Valiant, too?
I have to add my 2 cents here. How about a modern version of the 61-64 Corvair Rampside? I realize it probably couldn't be done today, due to safety issues, but mine is the most useful truck Ever! Nine foot bed, side ramp folds down, roll heavy stuff on/off. I have moved my entire garage and storage shed contents twice, totally by myself. OK, I used a hand truck and a cherry picker to lift my tool boxes on, but still....
