I think I would add a hyphen at the end of the first two lines:

Truppenfahrrad-
Unterstützungs-
Kasten

Note the connecting <s> at the end of Unterstützungs, too. For safety, you may want to go with all uppercase, BTW, to avoid the issue of whether the second and third lines would be capitalised or not.

Like in Dutch, there is no limit: you can always string more words together into a single compound noun. And IIRC, German doesn’t even have the spelling guideline that Dutch does, to use hyphens to visually separate parts of the word for legibility if you think that will be beneficial.
