I'm a big Univega fan, had an Alpina bought new in the nineties.
Its a great bike, as others said already, just not sure if it's the right ride as backpacking, long distance bike?
I have bit of experience, have ridden mine on bike packing trips to Austria and Tuscany back in time.
The steel frame and stays are pretty flexible, offer comfort and is quite light. But it has typically a sporty geometry as popular in the 90ties and a pretty short head tube, no suspension adopted fork till 1997 and therfore a really low front. Plus originally a flatbar and long flat stem.
I would rather keep my eyes open for an 700c Univega bike (via xxx series), those are more like a modern gravel bikes and offer a more comfortable riding position.
The Alpina would need at least a bit of tricks or creativity with regards to stem and bar combinations.
