The GM 14 bolt truck axle would be easier to find than an old 12 bolt car axle.
They have "floated axles" and are designed to carry a lot of weight.
12 bolt car rear ends are semi float, like the GM 10 bolt.

I get very good fuel milage empty even at 4000 feet above sea level. But it takes a TH700, 3.08 gears and a 6.5L with a big HE351VE turbo.
The setup conducive to good fuel milage isn't the best towing rig. I have had no problem towing between 6k and 7k when I was non-turbo with the factory setup using no more than a U-haul installed transmission cooler.
