From last weekend....to give you an impression how Airstreaming works on Germany Autobahn.
Legal towing speed for an Airstream is: 62 Mph.
Realistically most people drive 70-75 Mph with an Airstream.
On some places there is no speed limit for cars. You can drive as fast as you can even so advisory speed is 80 Mph.
Slower vehicles have to keep on the right lane and only use middle lane for passing other vehicles.
No passing by on the right site!
Typical speed for flowing traffic on Autobahn with no speed limit is around 100-130 Mph.
