Looks like Sportberger is a name used by Fritz Berger in Germany.

Fritz Berger is a camping supply and clothing company that has a large
catalog (418 pages) and lots of little camping accessories.  They do not sell
or convert campers.

My guess is that a Sportberger tent is just a generic bus tent with the name
sewn on.  It is very likely that this tent goes together just like all the
rest of the German bus tents.
