First of all, congratulations. No matter what kind of axles you have under your girl, you are now a member of the few, the proud, the vintage Airstream owners. You would be hard pressed to find a group of more enthusiastic and supportive vehicle owners. You can post any question--no matter how silly--and get answers here.
As you have already noticed, the forums have some, err, well, strong personalities. You might be surprised (or you might not) with the level of passion surrounding something as mundane as an axle. Dexter versus Henschen might as well be the American Civil War versus the War of Northern Aggression.
As for work, any older vehicle demands a certain level of attention. You can look at this as a pain... or as a "learning opportunity." Doing the work on a older trailer really teaches a person how systems function. I think the same principle is true whether we're talking about a car, a home or a trailer. The more you know, the more you feel in control of your own destiny. There is some measure in pride in being able to say, "Look what I bought," but it pales in comparison to being able to say, "Look what I built."
