If you've got a use for it, seems like a good candidate. Pictures not the best, can't tell if it's got duals in back, or even if all the wheels are there. Lots of coolness there, no doubt a seriously tough truck.
I doubt you'd ever get a running plow that size for less than $2500, but seems unlikely that you'd get too much cash out of it if you wanted to sell it down the road. There will undoubtedly be maintenance & repair issues, as on ANY old truck. In other words, don't expect to make money on the truck.
Now, making money WITH the truck, that's a whole 'nother subject . . .
