79 2wd shortbed or 86 4x4 longbed?

[Orion88]

So this past summer a friend of mine sold me a 79 2wd shortbed with 10,000 original miles. Zero rust, new hot rod black paint job and interior, new tires, runs like a top. If you crawl under the truck the tanks, frame rails, brake/fuel lines etc all look almost new. With winter fast approaching I'm starting to wonder if I should subject such a nice truck to midwestern winter conditions. On top of that it will be a handful in snow, even with the 500lbs worth of tube sand bags I have. My dad has an 86 4x4 longbed that he bought as a backup truck for his snow removal fleet. It has maybe only seen snow a few times and for being an original midwestern truck the body is in fantastic shape. Some rust is showing but it is still an extremely clean truck. So I'm debating on selling the 79 2wd and buying my dad's 86 4x4. Problem is, I'm not sure I will get what the 79 is worth with such low miles and in the condition it's in given the state of the economy. That being said, once I finish restoring my GTO there really won't be much of a point to owning the 79, seeing as it's basically a glorified El Camino the way she sits now. So I'm curious to hear your opinions on the matter.
