I built a second spare wheel for my Ural from two secondhand Dnepr wheels. I took the best hub of the two, ditto the rim and bought new spokes for any that were not serviceable.
Anyway, it was actually quite easy, as long as I did not rush, which meant walking away when I started getting impatient.
I found this site on wheel re-building
very handy for this, given that I had no prior experience. Have a look...
Adventure: it's an experience, not a style!
(so ride what you like, but ride it somewhere new!)
