Snow Chains on a Dually?

[dccarpenter]

I'm working on nursing my '67 LWB back to health as a daily driver but have been driving my dually and a '67 dually that's a buddy's as my daily driver in the mean time. It is a 2wd with regular tires(not bald but not snow tires)...it is awful in the snow/ice, I've never seen anything worse in my life.

If one of the rear tires is on ice when I park it gets completely stuck and can't get out unless I beat the ice with a hammer, throw down sand, curse a lot. I lived in New England for years so I know about rocking, feathering the e-brake, moving the tires left/right, I'm not a newbie to snow but this thing has NO traction whatsoever. With a one ton suspension adding weight to the bed has no effect, I'd have to drop 800 pounds in it to get any weight bearing on that axle.

I was thinking of getting some snow chains for the back to ts try and save some money as 4 snow tires are beyond my budget, would a chain on just the outer wheel work? Will it even be possible to get it on there since there is only an inch or so of space between the wheels? If not I'm guessing buying a Posi and installing myself will likely be cheaper than the snow tires. I help older relatives with shoveling&transport so getting around on the snow days is important.
