Why and how the text could be Bavarian

[oshfdk]

I don't get it—it's not really that different? Without the vowels, all the other words are just consonant clusters. It's very similar to that.

I don't think this would work as you describe. If you simply remove vowels from words, you'll get a lot of consonant clusters that won't appear in a running text. And certainly the length distribution of these clusters won't match the distribution of consonant clusters in a running text.
